The diazoalkane route has been used for the clean incorporation of diarylcarbene ligands into the organomanganese complexes of composition (η5-C5H4R)Mn(CO)2− thf (1, R = H; 2, R = CH3; thf = tetrahydrofuran), whose precursors are labile to substitution. The structure of the complex 4b derived from diazosuberon (3b) and exhibiting a seven-membered carbocyclic carbene ligand has been established by virtue
重氮烷路线已被用于diarylcarbene配体的清洁掺入的组合物(η的organomanganese络合物5 -C 5 H ^ 4 R)的Mn(CO)2- THF(1,R = H; 2,R = CH 3 ; thf =四氢呋喃),其前体对取代敏感。该复合物的结构图4b从diazosuberon(派生3B),并且表现出七元碳碳烯配体,已凭借单晶X射线衍射研究的(建立单斜,空间群Ç 2H 5 - P 2 / N;一个1045.6(4),b 789.9(4),c 2153.6(4)pm;β101.56(3)°; Z = 4;R = 0.075,R w = 0.059)。使用相同的合成方法,可以从1,4-双(重氮苄基)苯(3d)开始以52%的产率获得含有ω,ω'-双卡宾桥的双核化合物4d。对于η的合成方法上简单的程序2个-ketene络合物从金属卡宾的高压羰基化出现4b中和5b中。所述benzannelated
