摘要：

Reaction of CuI with equimolar amount of 2,6-bis(1-methyl-1H-pyrazol-3-yl)pyridine (bmppy) in MeCN and CH2Cl2 yielded a binuclear complex [(bmppy)Cu(mu-I)](2) (1). It was characterized by elemental analysis, IR, H-1 NMR and single crystal X-ray diffraction. Complex 1 possesses an iodide-bridged dimeric structure in which each Cu(l) center is tetrahedrally coordinated by two mu-I and two N atoms from one bmppy ligand. Complex 1 exhibited good catalytic performance in the polymerization of methyl methacrylate (MMA) in cyclohexanone. Even though the ratio of MMA to 1 was raised up to 1000:1 when the reaction time and temperature and the MMA concentration were fixed at 4 h and 80 degrees C and 3 mol/L, respectively, the polydispersity index (PDI) for the resulting PMMA is close to 1.36 and the conversion is up to 75%. In addition, the effects of solvents, reaction temperatures as well as the ratios of MMA to catalyst 1 were also investigated. (C) 2013 Elsevier B.V. All rights reserved.
