Abstract
worthy that this reaction did not proceed in the absence of cerium (II1) chloride. Trivalent cerium3 presumably plays dual roles in this reaction; it activates phosphine oxides by coordination so that the deoxygenation with LiAlH4 proceeds readily4 and it activates NaBH, to facilitate reaction with intermediates phosphines to form phosphine-borane^.^ This new method involves the following characteristic features:(1) Products are obtained directly ...
