摘要

The monobenzoylation of 1-phenyl-1, 2-ethanediol in the presence of different tin reagent has been studied. The stannylene ketal of 1-phenyl-1, 2-ethanediol has been prepared and used as a catalyst or generated in situ by exchange with other mixed tin ketals. In either case, the acylation occurs rapidly with 2mol% of the catalyst with the known selectivity. These experiments clearly establish the catalytic nature of the acylation reaction.
