Intermolecular Markovnikov-Selective Hydroacylation of Olefins Catalyzed by a Cationic Ruthenium–Hydride Complex

The cationic Ru–H complex was found to be an effective catalyst for the intermolecular hydroacylation of aryl-substituted olefins with aldehydes to form branched ketone products. The preliminary kinetic and spectroscopic studies elucidated a ruthenium-acyl complex as the key intermediate species. Th...

Summary:The cationic Ru–H complex was found to be an effective catalyst for the intermolecular hydroacylation of aryl-substituted olefins with aldehydes to form branched ketone products. The preliminary kinetic and spectroscopic studies elucidated a ruthenium-acyl complex as the key intermediate species. The catalytic method directly afforded branched ketone products in a highly regioselective manner while tolerating a number of heteroatom functional groups.
