Synergistic effect in the catalysis by pyridine N-oxide-triethylamine mixture of acyl transfer processes with participation of benzoyl, diethoxyphosphinoyl, and p-toluenesulfonyl chlorides

The kinetics of benzoylation of substituted phenols with benzoyl chloride in the presence of pyridine N-oxide-triethylamine was analyzed with regard to previously reported data on benzoylation, phosphorylation, and sulfonylation of phenols and carboxylic acids. A common mechanism of the synergistic effect was established. The synergistic effect decreases in the series PhCOCl (EtO)2POCl > TsCl.
