The reaction of esters with ethyl diazoacetate catalyzed by the complex [F27-Tp4Bo,3CF2CF3Ag(acetone)] generates α-(acyloxy)acetates in moderate to high yields. This is a novel transformation in the context of carbene-transfer reactions from diazo compounds that, according to experimental and theoretical data, is suggested to occur through zwitterionic intermediates.
