The synthesis and single-crystal X-ray structure of the first example of a tridentate, di-orthometallated triphenyl phosphite complex

Abstract

Reaction of [Ir(cod)(py)2][PF6] with triphenyl phosphite leads to the previously reported complex [Ir(cod){P(OC6H4)(OPh)2{P(OPh)3}], but reaction of [Ir(cod){P(OPh)3}Cl] with methyllithium and subsequent treatment with methanol yields the tridentate di-orthometallated complex [IrH(cod){P(OC6H4)2(OPh)}].
