摘要：

A metal-organic coordination polymer of [Mn-3(1,4-benzenedicarboxylate)(3)(DMF)(4)] ([Mn-3(BDC)(3)(DMF)(4)](n)) was synthesized and characterized by IR spectra, elemental analysis (CHN), thermal gravimetric analysis (TGA) and single crystal X-ray diffraction analysis. The structure of [Mn-3(BDC)(3)(DMF)(4)] is a 2D-periodic framework based on Mn(II)-terephthalate secondary building units (SBUs). The catalytic oxidation of various olefins was effectively carried out with [Mn-3(BDC)(3)(DMF)(4)](n). Moreover, the influence of key reaction parameters, including the solvents, reaction temperatures and nature of oxidant were studied. The optimized conditions were achieved by TBHP as the efficient oxidant in 1,2-dichloroethane solvent at 75 degrees C. Finally, this catalyst was used for four cycles efficiently without a significant loss of yield. (C) 2013 Elsevier Ltd. All rights reserved.
