通过TaCl_2Me_3与[Li_2 {C_5H_4CMe_2（C_2B_10H_10）}（OEt_2）_2]的盐复分解反应，合成了Cp-carboranyl配体的三甲基钽配合物。2当量的N-甲基-N-甲基-N-甲基-N-甲基咪唑与Ta（Cp-carboranyl）Me 3反应，生成含环外亚胺基的四元氮杂金属环化合物。通过Ta（Cp-碳硼烷基）Me 3与B（C6 F5）3（THF）反应生成了刘易斯碱稳定的阳离子物种。
A trimethyltantalum complex with a Cp-carboranyl ligand was prepared via a salt metathesis reaction of TaCl2Me3with [Li2{C5H4CMe2(C2B10H10)}(OEt2)2]. Two equivalents of carbodiimides reacted with Ta(Cp-carboranyl)Me3to form four-membered azametallacyclic compounds with an exocyclic imine group. A Lewis base stabilized cationic species was generated by the reaction of Ta(Cp-carboranyl)Me3with B(C6F5)3(THF).
