| 摘 要： | The title complex N,N-bis(2-benzoyl-3-oxobutane)-trans-1,2-diaminocyclohexane-palladium(C28H28N2PdO4) has been synthesized by the reaction of N,N-bis(2-benzoyl-3-oxobutane)-trans-1,2-diamino-cyclohexane with PdCl2,and characterized by elemental analysis,IR spectrum,WAXD and TG.The spatial structures of the complex have been confirmed by single-crystal X-ray diffraction analysis.The compound crystallizes in the monoclinic system,space group C2/c with a = 29.763(6),b = 10.320(2),c = 18.921(4) ,β = 102.75(3)°,V = 5668(2) 3,C28H28N2PdO4·CH3OH,Mr = 594.97,Z = 8,Dc = 1.394 g/cm3,μ(MoKα) = 0.694 mm-1,F(000) = 2448,T = 293(2) K,R = 0.0572 and wR = 0.1347(I 2(I)).The compound was investigated for the catalytic behavior towards norbornene(NB) vinyl addition polymerization.And the palladium complex showed excellent catalytic activity up to 9.97×106 g of PNB(mol of Pd)-1 h-1 with high monomer conversion using methylaluminoxane(MAO) as a cocatalyst.
