ChemCatChem, Vol. 6, págs. 2206-2210 (2014). DOI: 10.1002/cctc.2014022411867-3880https://hdl.handle.net/10272/27613The 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.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/CarbenesDiazo compoundsEster functionalizationSilverZwitterionsjournal article10.1002/cctc.201402241open access
