Rhenium(V) iododioxobis(triphenylphosphine) [ReO2I(PPh3)2] proved an effective metal catalyst for living radical polymerization of styrene in conjunction with alkyl iodides as initiators [R-I: CH3CH(Ph)I, (CH3)2C(CO2Et)I, and CH3CH(CO2Et)I] in the presence of Al(Oi-Pr)3. Compared to RuCl2(PPh3)3, the group 7 complex was highly effective for styrene, so as to induce living polymerization even at 30° to yield well-controlled polystyrene, with Mn up to ∼4 × 104 and narrow mol. weight distribution (MWD) (Mw/Mn = 1.19). The polystyrene thus obtained possessed one initiator moiety (R) at the α-end and one iodine atom at the ω-end, both from the initiator R-I, which indicates that the polymerization proceeds via activation of the C-I terminal, derived from R-I, by the Re(V) complex. Addition of methanol or water did not inhibit the polymerization, while a stable nitroxide radical (TEMPO) immediately and completely quenched it. The quenching experiments thereby supported intervention of radical species in the Re(V)-mediated living polymerization
