文摘

A trimethyltantalum complex with a Cp-carboranyl ligand was prepared via a salt metathesis reaction of TaCl₂Me₃ with [Li₂{C₅H₄CMe₂(C₂B₁₀H₁₀)}(OEt₂)₂]. Two equivalents of carbodiimides reacted with Ta(Cp-carboranyl)Me₃ to 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)Me₃ with B(C₆F₅)₃(THF).
