4-dimethylaminopyridine (DMAP) to generate electrophilic aroyl-DMAP salts is described. In contrast to classical carbonylation reactions, which often require nucleophiles to react with weakly electrophilic palladium-acyl intermediates, the high electrophilicity of aroyl-DMAP salts allows the acylation of a broad range of substrates. This transformation is mediated by a palladium-Xantphos catalyst, and mechanistic
