Reaction of [Ir(cod)(py)2][PF6] with PPh3 or P(C6H4-4-F)3 gives the bis(phosphine) derivative [Ir(cod)L2][PF6], but with the poorly basic phosphine P(C6H4-4-CF3)3 or AsPh3 the mixed ligand complexes [Ir(cod)L(py)][PF6] are obtained. The synthesis of [Ir(AsPh3)(cod)(PPh3)][CF3SO3] is described, and the structures of this and of [Ir(AsPh3)(cod)(py)][PF6] determined by X-ray crystallography. The use of
[Ir(cod)(py)2 ] [PF 6 ]与PPh 3或P(C 6 H 4 -4-F)3反应得到双(膦)衍
生物[Ir(cod)L 2 ] [PF 6 ],但是使用碱性较差的膦P(C 6 H 4 -4-CF 3)3或AsPh 3时,会得到混合的
配体配合物[Ir(cod)L(py)] [PF 6 ]。描述了[Ir(AsPh 3)(cod)(PPh 3)] [CF 3 SO 3 ]的合成,以及该化合物和[Ir(AsPh 3)(cod)(py)] [PF的结构图6由X射线晶体学测定。描述了将某些配合物用作
亚胺氢化的催化剂。
