Study of the Rh₂(OAc)₄‐ or BF₃·OEt₂‐Mediated Reaction of Thioacetic <i>S</i>‐Acid with α‐Diazocarbonyl Compounds

Abstract

Abstract The Rh 2 (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 BF 3 ·OEt 2 gives O ‐esters. The mechanism of the reaction is discussed. (© Wiley‐VCH Verlag GmbH &amp; Co. KGaA, 69451 Weinheim, Germany, 2003
