One set of transformations for which DMAP is commonly utilized is the acylation of hydroxyl group in the presence of acid anhydride. Looking for online definition of DMAP or what DMAP stands for? This data sheet reviews its applications as an acylation catalyst and in various other chemical disciplines. FT-IR, TG, SEM results illustrated that the DMAP was successfully immobilized on silica gel and the BET result suggested the pore structure was not altered after. The reaction mechanism has also been studied experimentally in dichloromethane through analysis of the reaction kinetics for the acetylation of cyclohexanol with acetic anhydride, in the presence of DMAP as catalyst and triethylamine as the auxiliary base. Common Uses: Nucleophilic catalyst for Boc protections The first novel and efficient chiral DMAP-thiourea bifunctional catalyst has been successfully developed and applied in highly enantioselective acyl-transfer reactions.
