Catalyst deactivation during rhodium complex‐catalyzed propargylic C−H activation
Abstract: In this study, the complete mechanistic elucidation of rhodium-catalyzed propargylic C−H activation is presented. Particular attention is paid to the deactivation pathway of the catalytic reaction. The associated deactivated species has been studied in detail by NMR and Raman spectroscopy as well as X-ray crystallography. Furthermore, the present work includes a kinetic study carried out by in situ operando NMR spectroscopy.
Detailed mechanistic investigations on our previously reported synthesis of branched allylic esters by the rhodium complex-catalyzed propargylic C−H activation have been carried out. Based on initial mechanistic studies, we present herein more detailed investigations of the reaction mechanism. For this, various analytical (NMR, X-ray crystal structure analysis, Raman) and kinetic methods were used to characterize the formation of intermediates under the reaction conditions. The knowledge obtained by this was used to further optimize the previous conditions and generate a more active catalytic system
