摘要

Reaction of the triamidostannates(II) MeSi{SiMe2N(3,5-xyl)}(3)SnLi(OEt2) (2a) and MeSi{SiMe2N(p-tol)}(3)SnLi(OEt2) (2b) with [IrCl(CO)(PPh3)(2)] gave the Ir-1-Sn complex [MeSi{SiMe2N(3,5-xyl)}(3)SnIr(PPh3)(2)(CO)] (3a) for the former. In contrast, for the tolyl stannate CH-activation occurred to give the Ir-III 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.
