Single electron transfer (SET) reactions are effected by the combination of a MesP/B(CF) frustrated Lewis pair with benzoyl peroxide derivatives. The resulting homolytic cleavage of the peroxide bonds affords the radical salts [MesP˙][RCOOB(CF)] (R = Ph 1, p-BrCH2, p-MeCH3). These species react with PhSnH to give [MesPH][RCOOB(CF)] (R = Ph 10, p-BrCH11, p-MeCH12) and (PhSn). The mechanism of these SET reactions is discussed in light of control experiments and DFT calculations.
