The reaction of esters with ethyl diazoacetate catalyzed by the complex [F<inf>27</inf>-Tp<sup>4Bo,3CF2CF3</sup>Ag(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. © 2014 WILEY-VCH Verlag GmbH & Co.
