TīmeklisThe thiol–epoxy reaction is strongly autocatalytic due to the formation of hydroxyl groups that facilitate the ring-opening of the epoxy group. 16 The reaction mechanism can become more complex in the presence of nucleophilic tertiary amine catalysts, such as benzyldimethylamine (BDMA) and 1-methylimidazole (1MI), which lead to a very … Tīmeklis3 324 15.3: Preparation of Alcohols By Reduction of Carboxylic Acids and Esters - LiAlH 4 (but not NaBH 4 or catalytic hydrogenation).
