- Mr. Explosions&Fire Extractions&Ire aka Australian man aka Tom has been playing Minecraft for 3 years straight. It is time to stop him.
In this video I am making [1.1.1]Propellane starting with the chlorination of Pentaerythritol, followed by alcohol oxidation and decarboxylation. The resulting terminal alkene is then reacted with the dibromo carbene which is formed from Bromoform. The resulting dibromo dichloro product is then subjected to a double transmetalation with methyllithium to form [1.1.1]Propellane.

I love how everyone is talking about the cubane synthesis to make Tom finish it
it's the fucking best
Tom’s fuckin GameCube intro gets me every time 😂
I support chemistry based peer pressuring
We call it cheer pressure
we get to chemistry vicariously through Sam :)
Your a fun guy I see .
@@yougottrolledbythebest8117 perhaps
C'mon man it's not a crack shed, it's a cocaine shed in the very least
Crack is higher purity, so that's definitely out of place there
@Nathan Smith what? Crack is diluted cocaine
Tom's hydrazine cabin
@@thecountrychemist2561 no it is not. It is freebase cocaine, and usually separates out at a really high purity. Crack tends to be 90%+ while powder is rarely above 85% coming out of Mexico then gets cut further throughout the supply chain. Base extraction is an effective means of purifying most amines
@@charlesnathansmith How do you know that (totally not a fed)
One of the PhDs in my lab did a lot of work on Propellane and similar molecules. After he defended our group made him a "doctor hat" which is a traditional thing here, and at the top of the hat I added a giant 3D printed propellane molecule powered by servos that would rise up and spin around when you pressed a button.
Mikä yliopisto?
That's honestly so sweet
WHERE IS THE VIDEO?????
I love that you seem to invest in reagents and stuff. Like, I get the whole "only hardware store chemicals" concept, but sometimes you just wanna watch someone pop a fresh bottle of commercial methyllithium, y'know.
Cube: who are you
Propellane: im the captain now
I live for E&F shade in chemistry youtube these days.
I think it's amazing how Tom has single handedly entered "Yellow Chemistry BAD" into the collective subconscious of chemistry enthusiasts worldwide
Hope he drinks lots of fluids 😂
I love how your channel started as a "proper" chemistry vlog and then it slowly Chad-ified into what it is today. Please keep going this style is awesome
Edit: OMG the 18-crown-6 has returned!!
Ya that chemical really takes the crown. heh
Things I absolutely love about this channel:
-The subtle humour: text smileys, appropriate emoji/regular memes
-The inclusion of mechanisms
-"I can finally *propel* myself out of here
-Yellow chem pain is not ignored
-Many more to come
I love how this guy is going more insane in every single video 😂
Where's the insane?
I can't express how much I love this channel. High quality and exciting chemistry, good explanations and exactly my kind of humor. Keep doing what you do!
I love this kind of humor coupled with solid chemistry, AAA content my man
also nice explanation of the mechanism!
Super cool, loved to see the mechanisms behind this, takes me back to OCHEM.
Also, 69% yield. Nice.
I like the green highlight during the mechanism explainer phase, makes those of us not too familiar with chemical synthesis able to follow along.
A useful tip for doing those types of dihalocyclopropanations is to add the NaOH over a period of time, and not all at once. This helps to generate a fresh amount of carbene and will increase the yield.
Always a good day when you can break out the Gigachad molecule 18-crown-6
That’s a great final yield, it’s my favorite number
Just wanna say that I lovr your new green highlighting during mechanisms! Can't believe you still manage to improve.
Love the little green circle in the reaction breakdowns, helps my small brain understand
You had a lot of fun with this one
You really have to give him PROPs
...
I'll see myself out
That Chemist called. He says this is cursed.
Love that you show the reaction mechanisms 🙏🏻 makes me really appreciate what I’ve learned in Orgo so far
at this point youtube chem is starting to become just nano-scale solid geometry lmao
This is a great mix of Nile red and explosions and fire. The perfect mix of two extremes.
Drake shunning the cube dismissively, then smiling approvingly at weird propeller thing.
Excellent work. Very easy to follow, thanks for showing the reaction mechanisms.
I love your videos, because you're the person who DOES "in more detail..." bits. If it was boring, I can skip it, but if it wasn't there I couldn't just summon all that knowledge from ether xD
Try microwave assisted chemistry for the carbene synthesis step. The crown catalysts work extremely well with microwaves
Yeahhhh he uploaded!!!!
Fantastic! That is what I call “good old chem”. You just nailed that propellane .
E&F is going to make it, i believe it
Right on I think I've only ever seen one other thing to do with pentaerythritol. Badass thank you
Thank you for this organic tour de force! OChem is my absolute favorite and difficult synthetic schemes are even better.
I love all puns in this video XD Who needs cube when you can propel yourself through chemistry XD
Great work!
YES FINALLY A PROPELLANE ENJOYER YEEES
Pretty cool! I been watching the Cubane synthesis saga. This might've been the first time one of those lil chemical equation diagram thangs has made sense in my mind.... Thanks for sharing!
a yield of 69% reminds me of another type of Saga...
Great video thanks for sharing
Amazing. Very well done! Keep it up :)
I really enjoyed this one
Its amazing what you can do with a proper budget
Wow. That looks like it takes at least a day between all of those steps.
penta Er and hno3 are quite a spicy mix in other contexts
If for some reason the chlorination does not go to completion, you might get some jumpy esters.
I Officially love this channel
Sounds like you were smiling through most of the narration on this one 😁
Amazing work!
Neat! Now waiting for smt like tetrahedrane!
great video, i'm surprised during the MeLi step, that the major product isn't formed from MeLi doing NS on the carbons bearing chlorine. Also i would have expected some dimers and trimers forming during this step.
Do you or the authors have any explaination of why the systems seems to prefer forming this creazy strained propellane ?
Great video dude!!
Pinacol is the pinnacle of compounds.

Yes, now make all the different hydrocarbon cyclic molecules
Absolute legend
Nicely done. Tom (the guy with the crack shed) is probably gonna mention you in an upcoming video!
This is incredible, and very enjoyable to watch (as always, actually 😊). I do have some constructive criticism about the handling of the MeLi in the video, if you're interested.
You earnt my sub with just that intro haha
Interesting stuff - side quest completed
Poor molecule, it wants to get rid of the central bond as much as any woman wants to get rid of her bra at the end of the day.
I love that intro lol! I'm also surprised at how relatively easy it is to synthesize such an unstable, strained compound. I assumed that, aside from the dibenzo 18 crown 6, it would require some weird exotic reagents and/or UV light, like with cubane.
Edit: I read about it, and the propellane can undergo a polymerization reaction to form various staffanes. I wonder if these compounds have any energetic properties if they're combined with suitable oxidizers.
Not an expert in this, but my understanding is that strain plays a pretty small role where things that really want to be gases play a much bigger one.
@@davidfetter Ring strained hydrocarbons have been used as fuels in rocket propellant for liquid rocket engines. The ring strain does contribute to the ISP (efficiency). Many of them tend to have quite high density for hydrocarbons, and they have favourable melting points as well, tending to not require as much insulation to prevent them from freezing on the tank walls when exposed to the vacuum of space.
You are right that they’re a bit rubbish for explosives, however. Ring strained nitrogen heterocycles are pretty great though! There are some interesting bicylic and tricyclic ones! They have quite high performance but tends to be quite friction sensitive - for both high performance and good handling characteristics you want aromatic nitrogen heterocycles instead as their aromaticity stabilises them, the whole molecule absorbing strain rather than just one or two bonds upon energy input
Amazing job well done how are you
Damn this chemistry's getting good!
Nice nice nice^^ needed to be sayed… that green dot is lit :) I like it
I’m ending school chemistry soon.
My life never will be the same after this video…
This channel has to grow
I wonder if the propellane can polymerize to form polypropellane.
I see, the polymer is called staffane. Sure.
Is there a reason why you directly dry the liquids with MgSO4 and don't use a previous drying step with concentrated NaCl solution (in the seperatory funnel?)
At least this was the way I was taught it back then 😅
Am I the only one who absolutely fucking LOSES IT! Every time he says "I set the filtrate up for Short Path Vacuum Distillation."
the next video would be tetrahedrane)
btw, we are doing propellans here each day. so nice to see it here too (love)
Nice final yield
I'm new to this channel and I already love how water is called dihydrogen monoxide
I do wonder. How one can acquire so much knowledge about all of the proper procedures and how to set up the synthesis reactions to such perfection as I see it in this video? Also how to know what clean up steps are necessary?
Learning and shrooms lots of adderall too-Thomas Edison
You know what is better? Just do both :)
Shots fired I see
How do you have access to all of these chemicals? DCM is near impossible to obtain in the US, much less thionyl chloride, unless you’re a licensed lab.
Also I’d suggest adding your solvent to dry ice already in a container, ideally a dewar rather than a glass container, it splashes and bubbles way less and comes down to temp much faster
Nice yield!
What is the composition of the tar?
Sweet 187 step synthesis.
I couldn't hear him, what does he add to the isopropyl to make that -70c bath in the last step?
dry ice (Adding isopropyl alcohol to dry ice makes the liquid cool very quickly ⏤ the mixture's temperature can reach -90°C (-130°F))
@@rubenklobertanz4675 thank you so much

The best shape was already there i.e. shape of benzene because
"Hexagons are Bestagons" - CGP Grey
Ok Senku😃
4:20 I think it's better to pour your mixture into (ice) water. This should produce larger particles making the filtration easier
Using “heavy” water more interesting honestly . Try it out.
Idea for a video: chloromethyl furfural chemistry (supposedly one of the most promising celllose-sourced raw materials, with the possibility of turning it into polymers, fuels etc)
Molecular origami. Love it.
Can we combine washing steps, magnesium sulfate, filtering and short-path vacuum distillation into a single "standard cleaning" step in video? It happens so often that I'm unsure if there's anyone who didn't learn it by heart yet :)
5:11 put "the thing"back in 😱😱😭😭 it still has some stuck to it. Ohh and can to try to make dinitro acetylene
You're my hero
thiophenol has such a memorable smell... but its almost like meaty at really low concentration
As an avid viewer of explosions and fire, can confirm it is in fact a crack shed
I noticed you were from the Netherlands, may I ask where you have studied?
That Aussie crack shed filled with yellow stuff going boom, is a bit sus... 🤨
😁
What about square based or triangular based pyramids?
Yes propellane army letsgoooooooo!
Nitrate this and it would make an extremely potent energetic material.
Can you add link to the methodology, pls?
7:33 T A R 🎉
This dude just casually glossing over using 73mL of thionyl chloride, like it's a reagent you can pick up from Home Depot. lol.
Love your content :-)
Now make a molecular swivel joint to attach it to
Propellane go brrrrrrr
My spirit chemical
I didn't quite have all the reagents and equipment, so after a few substitutions I wound up with banana bread. Help?
