Stereospecific free-radical addition of menthyl phenylphosphinate to cyclohexene: evidence for retention of configuration at phosphorus

Abstract

In contradistinction to a recent report that the free-radical addition of menthyl methylphosphinate to alkenes proceeds with inversion of configuration at phosphorus, dibenzoyl peroxide-catalysed addition of menthyl phenylphosphinate to cyclohexene occurs with retention of configuration.
