Rhenium(V) iododioxobis(triphenylphosphine) [ReO2I(PPh3)2], a group 7 transition metal complex, induced living radical polymerizations of Me and Bu acrylates in conjunction with an iodide initiator such as CH3CH(Ph)I and (CH3)2C(CO2Et)I in the presence of Al(Oi-Pr)3, where the reaction was faster than the NiBr2(Pn-Bu3)2-mediated. The number-average mol. weights of the obtained polymers increased in direct proportion to monomer conversion, and the mol. weight distributions were relatively narrow throughout the polymerizations (Mw/Mn ∼ 1.6). The polymerization most probably proceeds via the rhenium-catalyzed homolytic cleavage of the polymer C-I terminal originated from the iodide initiator, as indicated by the 1H NMR anal. of the polymer terminal structure and quenching study of the polymerization with a stable nitroxide radical. In contrast, a bromide initiator like CCl3Br led to an uncontrolled acrylate polymerization with the rhenium(V) complex. The iodide/ReO2I(PPh3)2 initiating system also induced a fast polymerization of Me methacrylate, though the polymerization was not controlled.
