investigated in detail. For dihydrogen transfers the tendency of dihydroaromatics to disproportionate into tetrahydro-aromatic and aromatic hydrocarbons was evaluated for 1,2- and 1,4-dihydrobenzenes, 1,2- and 1,4-dihydronaphthalenes and 9,10-dihydroanthracene toward (Cod)2Ni, Bpy(Cod)Ni and (Et3P)4Ni. The catalyzed disproportionation, which proceeded with decreasing rate in the order, 1,4-C6H8 > 1,2-C6H8 > 1
在研究二氢和氢化铝转移至不饱和烃之间可能的机理相似性时,详细研究了镍(0)配合物对此类转移的催化作用。对于二氢转移,评估了1,2-和1,4-二氢苯,1,2-和1,4-二氢萘和9,10-二氢蒽朝向(鳕鱼)的二氢芳烃歧化成四氢芳烃和芳烃的趋势。2 Ni,Bpy(Cod)Ni和(Et 3 P)4 Ni。催化歧化以递减的顺序进行,依次为1,4-C 6 H 8 > 1,2-C 6 H 8 > 1,2-和1,4-C 10 H10 »9,10-C 14 H 12解释为中间烯丙基氢化镍的形成。
