  Phosphoranyl radicals as reducing agents: SRN1 chains with onium salts and neutral nucleophiles

  摘要：

  Redox radical chain reactions of trivalent organophosphorus compounds (PZ3) with diaryliodonium (Ar2I+) and triarylsulfonium (Ar3S+) salts to give arylphosphonium (ArP+Z3) salts and iodoarenes (ArI) or diaryl sulfides (Ar2S) are reported. The key propagation step in these SRNI reactions is a single-electron reduction of the onium salts by intermediate phosphoranyl radicals (ArPZ3). The observation of competitions between solvent molecules and phosphine establishes the intermediacy of free aryl radicals and allows estimates of rate constants for addition of p-tolyl radicals to triphenylphosphine (k almost-equal-to 3 x 10(8) M-1 s-1) and to trimethyl phosphite (k almost-equal-to 2 x 10(8) M-1 s-1). The intermediate phosphoranyl radicals can also partition between competitive reaction pathways; the aryltributylphosphoranyl radical, ArPBu3, for example, partitions between unimolecular alpha-cleavage of butyl radical and chain-propagating electron transfer to diaryliodonium salt. The relative amounts of these two pathways allows an estimate of the rate constant for electron transfer, k(SET) almost-equal-to 4 X 10(9) M-1 s-1.
