Abstract
Reaction of IrCl (CO)(PPh3)2 with silver perchlorate in various solvents gives [Ir(CO)(solvent)(PPh3)2]ClO4. Crystalline salts have been isolated where solvent = acetonitrile, benzonitrile, and dimethyl sulphoxide. [Ir(CO)(CH3CN)(PPh3)2]+ redily undergoes substitution reactions with carbon monoxide, phosphines, and isocyanides and, the following cations hsve been characterised: [Ir(CO)3(PPh3)2]+, [Ir(CO)(PPh3)3]+, [Ir(CO)(PPh2Me3)]+, [Ir(CO)(PPh2Et)3]+, [Ir(PPh2Me)4]+, [Ir(CO)(Ph2PCHCHPPh2)2]+, [Ir(CO)(p-Tolylisocyanide)(PPh3)2]+ and [Ir(p-tolylisocyanide)3(PPh3)2]+Keywords
