• organophosphorus compounds: the phosphinates R1R2P(O)(OR) [9]. Because the phosphinic acid moiety P(O)OH can mimic carboxylic acids, its incorporation into heterocycles may offer new opportunities for the discovery of biologically active analogs. However, little or no biological data is available at this time

• 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. Keywords: addition; free radical; homolysis; phosphine; radical; substitution; Introduction Organophosphorus compounds constitute an important class of

Namely, the thermal lability of the transition-metal-complexed 3H-benzophosphepine 33 was explored by Lammertsma et al. for the synthesis of a variety of organophosphorus compounds by means of [1
