Skeletal Reorganization of Enynes Catalyzed by a Ru(II)–Ru(III) Mixed-valence Complex under an Atmosphere of O2 or CO

Abstract

Abstract A mixed-valence Ru(II)–Ru(III) complex was used to catalyze the skeletal reorganization of 1,6-enynes, leading to the production of 1-vinylcyclopentene derivatives. The reaction proceeded optimally in an atmosphere of O2 or CO. The presence of an alkyl group at the internal olefinic carbon in the starting enyne resulted in an increase in product yield compared to that bearing no substituent on the olefin moiety.
