AbstractReaction of the triamidostannates(II) MeSi{SiMe2N(3,5‐xyl)}3SnLi(OEt2) (2a) and MeSi{SiMe2N(p‐tol)}3SnLi(OEt2) (2b) with [IrCl(CO)(PPh3)2] gave the IrI‐Sn complex [MeSi{SiMe2N(3,5‐xyl)}3SnIr(PPh3)2(CO)] (3a) for the former. In contrast, for the tolyl stannate CH‐activation occurred to give the IrIII compound [MeSi{SiMe2N(p‐tol)}2{SiMe2N(2‐C6H3‐4‐CH3)}SnIr(H)(PPh3)2(CO)] (3b). The latter is thus avoided by introduction of suitably placed substituents in the peripheral aryl groups of the triamidostannate ligand.
