Homolytic substitution at phosphorus for C-P bond formation in organic synthesis.

Organophosphorus compounds are important in organic chemistry. This review article covers emerging, powerful synthetic approaches to organophosphorus compounds by homolytic substitution at phosphorus with a carbon-centered radical. Phosphination reagents include diphosphines, chalcogenophosphines and stannylphosphines, which bear a weak P-heteroatom bond for homolysis. This article deals with two transformations, radical phosphination by addition across unsaturated C-C bonds and substitution of organic halides.
