    In this video, you’ll learn how to protect the acidic proton of an alcohol from strongly basic reagents like alkynide ions and Grignard reagents by forming the trimethyl silyl ether using TMS-Cl. You’ll see a detailed breakdown of the reaction and mechanism of the alcohol protecting group - TMSO and learn how to deprotect the alcohol with the use of tetrabutyl ammonium fluoride - TBAF.

    Can we deprotect TMS using H3O+???

    • @Leah4sci
      @Leah4sci  Pƙed 2 lety

      I believe that a strong acid in a THF/water solution would also work. But TBAF is the more commonly used method.
