## Abstract The use of intramolecular homolytic substitution at the sulfur atom by aryl and vinyl radicals, as an alternative to the use of alkyl halides, and chalcogenides as radical precursors in organic synthesis is reviewed.
The bisand tris(diazomethyl)phosphanes 5 and12 , obtained by electrophilic diasoalkane substitution of 4 or PC13 with lithiated 3 , are starting materials for complicated, heteroatom-substituted compounds. Thus, [3+2]-cycloadditions with the phosphaalkyne 9 and subsequent [1,5]-Tms shifts give rise
