摘要
The title complex N,N＇-bis（2-benzoyl-3-oxobutane）-trans-l,2-diaminocyclo- hexane-palladium （C28H28N2PdO4） has been synthesized by the reaction of N,N＇-bis（2- benzoyl-3-oxobutane）-trans-l,2-diamino-cyclohexane with PdCI2, and characterized by ele- mental 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） A, fl = 102.75（3）°, V = 5668（2） A3, C28H28N2PdO4·CH3OH, Mr = 594.97, Z = 8, Dc = 1.394 g/cm3, μ（MoKa） = 0.694 mm-1, F（000） = 2448, T= 293（2） K, R = 0.0572 and wR = 0.1347 （I〉 2σ（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 9.97x 106g of PNB （mol of Pd）-1 h-1 with high monomer conversion using methylaluminoxane （MAO） as a cocatalyst.
