(R)-(+)-5,5'-Bis(diphenylphosphino)-4,4'-bi-1,3-benzodioxole is a chiral nitrogen nucleophile that can be used as an asymmetric catalyst in the hydrogenation of prochiral substrates. It is synthesized by a palladium-mediated reaction between 2-bromoacetophenone and diphenylphosphine oxide. The enantiomers of the product are separated by column chromatography on silica gel with hexane/dichloromethane (90:10) as eluent. The (R)-enantiomer has been shown to be more active than the (S)-enantiomer in hydrogenating racemic substrates such as propanal and cyclopentanone.
