The interaction of phosphine nickel complexes Ni(PPh3)3 and Ni(PPh3)2(η2-C2H4) with methyl derivatives of methylenecyclopropane and cyclopropene has been studied. The novel olefin complexes: (η2-2,2-dimethyl-1-methylenecyclopropane)bis(triphenylphosphine)nickel, (η2-1,3,3-trimethylcyclopropene)bis(triphenylphosphine)nickel and (η2-tetramethylcyclopropene)bis(triphenylphosphine)nickel have been prepared
膦镍的相互作用络合的Ni(PPH 3)3和Ni(PPH 3)2(η 2 -C 2 H ^ 4亚甲基环丙烷和环丙烯)与甲基衍生物进行了研究。新颖的烯烃络合物:(η 2 -2,2-二甲基-1-亚甲基环丙烷)双(三苯基膦)镍,(η 2 -1,3,3- trimethylcyclopropene)双(三苯基膦)镍和(η 2 -tetramethylcyclopropene)双已经制备了(三苯膦)镍。在1 H和31 P 1的基础上讨论了所得化合物的结构。1 H NMR谱。在η的取代反应得到的复合物的反应性的比较研究2点的α-烯烃的配体进行说明。
