Resumen: The iridium complex [Ir(µ-CF3SO3)(¿2-NSiMe2)2]2 (3) (NSiMe2 = {4-methylpyridine-2-yloxy}dimethylsilyl) has been prepared by reaction of [Ir(µ-Cl)(¿2-NSiMe2)2]2 (1) with two equivalents of AgCF3SO3. The solid structure of 3 evidenced its dinuclear nature, being a rare example of an iridium species with triflate groups acting as bridges. The 3-catalyzed reduction of CO2 with HSiMe(OSiMe3)2 affords a mixture of the corresponding silylformate and methoxysilane together with the silylcarbonate CH3OCO2SiMe(OSiMe3)2 (4a). This is the first time that the formation of silylcarbonates has been observed from the catalytic reduction of CO2 with silanes. Analogous behaviour has been observed when HSiMe2Ph and HSiMePh2 were used as reductants.
