Photochemical isomerizations and related reactions of some tertiary phosphine- and tertiary arsine-iridium(III) complexes
Abstract
The photochemical isomerization of complexes of the types mer-[IrX3L3], [IrHX2L3], and [IrX3(CO)L2](X = Cl, Br, or I; L = tertiary phosphine) are reported. Complexes of the type fac-[IrX3(PEt3)3](X = CNO, SCN, or N3) have been made from mer-[IrCl3(PEt3)3] by a light-induced reaction. The complexes mer-[IrCl3L3](L = PEt3, PBun3, or AsMe2Ph) react with PMe2Ph in light to give [IrCl3L2(PMe2Ph)]. Some reactions of complexes of the type fac-[IrX3L3] are described.
