Controlled radical polymerization of alkyl acrylates and styrene using a half-sandwich molybdenum(III) complex containing diazadiene ligands

Résumé

The half-sandwich molybdenum(III) complex CpMoCl2(iPr2-dad) (iPr2-dad=iPr–N=CH–CH=N–iPr) proved to be an effective metal catalyst for the controlled radical polymerization of methyl acrylate, butyl acrylate, and styrene. In conjunction with an alkyl iodide [R–I: CH3CH(COOEt)I] as an initiator and in the presence or absence of Al(O–i-Pr)3 as a co-catalyst, the molybdenum-based system gave polymers with narrow molecular weight distributions. The in situ addition of styrene to a macroinitiator of poly(methylacrylate) afforded an AB-type block copolymer.
