摘要

Phosphine borane complexes are transformed under mild conditions, in presence of an olefin, into quaternary phosphonium salts by reaction with an alkyl (or aryl) halide. In the case of the reaction of (R)-PAMP. BH31e with benzyl bromide, the enantiomerically pure phosphonium salt 3h is obtained.
