Abstract
Chiral phosphorus(III) ligands with chirality residing on the phosphorus atom have seen a renaissance upon the discovery that coordination to boron stabilises the phosphorus atom towards both oxidation and racemization. In this review we describe the newer methods that are available for the preparation of P-chirogenic ligands and discuss their advantages and limitations.
Keywords: phosphorus, iigand, p-chirogenic, borane, chiral, asymmetric synthesis
