4-(N,N-Dimethylamino)pyridine hydrochloride as a recyclable catalyst for acylation of inert alcohols: substrate scope and reaction mechanism.


4-(N,N-Dimethylamino)pyridine hydrochloride (DMAP·HCl), a DMAP salt with the simplest structure, was used as a recyclable catalyst for the acylation of inert alcohols and phenols under base-free conditions. The reaction mechanism was investigated in detail for the first time; DMAP·HCl and the acylating reagent directly formed N-acyl-4-(N',N'-dimethylamino… (More)
