The reactions of vinyl chloride (VC) with representative late metal, single-site olefin dimerization and polymerization catalysts have been investigated. VC coordinates more weakly than ethylene or propylene to the simple catalyst (Me(2)bipy)PdMe(+) (Me(2)bipy = 4,4'-Me(2)-2,2'-bipyridine). Insertion rates of (Me(2)bipy)Pd(Me)(olefin)(+) species vary in the order VC > ethylene > propylene. The VC complexes
已经研究了氯乙烯 (VC) 与代表性的后期金属、单中心烯烃二聚和聚合催化剂的反应。VC 与简单催化剂 (Me(2)bipy)PdMe(+) (Me(2)bipy = 4,4'-Me(2)-2,2'-bipyridine) 的协调比乙烯或丙烯更弱。(Me(2)bipy)Pd(Me)(烯烃)(+) 物种的插入率按 VC > 乙烯 > 丙烯的顺序变化。VC 复合物 (Me(2)bipy)Pd(Me)(VC)(+) 和 (alpha-diimine)Pd(Me)(VC)(+) (alpha-diimine = (2,6-(i)Pr (2)[bond]C(6)H(3))N[双键]CMeCMe[双键]N(2,6-(i)Pr(2)[bond]C(6)H(3)) ) 经历净 1,2 VC 插入和 β-Cl 消除以产生 Pd[键]Cl 物质和丙烯。(吡啶-双亚胺)MCl(2)/MAO 催化剂(M = Fe,
