| Abstract: | Treatment of Cp*IrH(SH)(PMe3)] (Cp* = eta5-C5Me5) with IrCl2(NO)(PPh3)2] in the presence of triethylamine yielded the sulfido-bridged Ir(II)Ir0 complex Cp*Ir(PMe3)(mu-S)Ir(NO)(PPh3)], which further reacted with I2 and triflic acid to give the diiodo complex Cp*Ir(PMe3)(mu-I)(mu-S)IrI(NO)(PPh3)] and the hydrido complex Cp*Ir(PMe3)(mu-H)(mu-S)Ir(NO)(PPh3)]OSO2CF3], respectively. |
