The N,Nâ²-bis(sulfonyl)diaminosilane TsdmsinH2 (TsdmsinH2 = (CH3)2Si(NHTs)2, Ts = p-CH3C6H4SO2) reacted with [Cp*IrCl2]2 (Cp* = η5-C5(CH3)5) in the presence of a base to give the coordinatively unsaturated (silylenediamido)iridium complex [Cp*Ir(Tsdmsin)] (2), which was further converted to the 18e adducts [Cp*Ir(Tsdmsin)L] (L = P(C6H5)3 (3a), P(OC2H5)3, CO); the reactions of 2 and 3a with water led to the formation of the imido-bridged dinuclear complex [Cp*Ir(µ2-NTs)2IrCp*] and the bis(amido) complex [Cp*Ir(NHTs)2P(C6H5)3}], respectively.
