✦ Synopsis

Reduction of phosphinic acids (I) with phenylsilane or of the corresponding diacids (V) with LiAlH 4 provides phosphines (II) or diphosphines (III) via their acid chlorides. They may be used in Michael additions with the activated alkene (V) or in most cases as stable borane adducts such as (VII) and (X) to yield a variety of phosphinic and diphosphinic ligands. -(SOULIER, E.;
