Rhodium-catalyzed P–P bond exchange reaction of diphosphine disulfides?
Chemical Communications Pub Date: 2016-10-26 DOI: 10.1039/C6CC07302F
Abstract
A rhodium-catalyzed exchange reaction of diphosphine disulfides, a diphosphine oxide, and a diphosphine is developed. Various symmetric diphosphine disulfides containing alkyl and phenyl groups are exchanged, giving equilibrium mixtures, from which unsymmetric diphosphine disulfides are readily separated by silica gel chromatography. The resulting unsymmetric diphosphine disulfide is regioselectively added to an aldehyde.
