Abstract

Abstract: Remarkably simple Ir III catalysts enable the isomerization of primary and sec ‐allylic alcohols under very mild reaction conditions. X‐ray absorption spectroscopy (XAS) and mass spectrometry (MS) studies indicate that the catalysts, with the general formula [Cp*Ir III ], require a halide ligand for catalytic activity, but no additives or additional ligands are needed. Abstract : The allylic job : A remarkably simple and general family of catalysts for isomerizing both primary and sec ‐allylic alcohols is reported. The catalysts, with the general formula [Cp*Ir III ], only require a halide ligand for optimal activity, with no additional additive or ligand needed. A mechanism is proposed based on kinetic investigations and isotopic labeling experiments.
