title: Radical alkylphosphanylation of olefins with stannylated or silylated phosphanes and alkyl iodides.
abstract: Intermolecular conjugate radical addition reactions of secondary and tertiary alkyl radicals derived from the corresponding alkyl iodides to activated olefins such as α,β-unsaturated esters, amides, imides, nitriles, and sulfones are described. The adduct radicals are trapped by either diphenyl(trimethylstannyl)phosphane or the commercially available diphenyl(trimethylsilyl)phosphane as chain transfer reagents to give the corresponding phosphanylated products in moderate to good yields. The overall process comprises a C-C followed by a C-P bond formation.
