Reactions of Silanes and Silyl Halides with Trans-MeIr(CO)[P(p-tolyl)₃]₂, Carbon–Hydrogen and Carbon–Silicon Bond Formation

Abstract

Reaction of silanes (HSiR,, R, = Me,Ph, (OMe),) with trans-MeIr(CO)[P(p-tolyl),], leads to methane and Hlr(SiR,),(CO)[P(p-tolyl),], through oxidative addition and reductive elimination sequences. These reactions contrast with those involving the addition of silanes to analogous alkoxo iridium complexes. Reaction of Me,SiI with rrans-MeIr(CO)[P@-tolyl),], produces Me. $ and Ir(SiMe,)(CO)[P(p-tolyl),],I,, thus providing the first example of oxidative addition of silicon-iodide bonds at ambient conditions. These reactions demonstrate the formation of carbon-hydrogen and silicon-carbon bonds.
