Abstrakt: The Rh2(OAc)4-catalyzed reaction of methyl aryldiazoacetates with thioacetic S-acid gives exclusively the S−H insertion products in high yields, while the corresponding reaction mediated by BF3·OEt2 gives O-esters. The mechanism of the reaction is discussed. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003
