| Abstract | CH2}RhH(CO) (12) and {PhB(Ox(Me2))(2)Im(Mes)}IrH(Ph)CO (13). In 12, oxidative addition results in cyclometalation of the mesityl ortho-methyl similar to 10, whereas the iridium compound reacts with the benzene solvent to give a rare crystallographically characterized cis-[Ir](H)(Ph) complex. Alternatively, the rhodium carbonyl 5 or iridium isocyanide {PhB(Ox(Me2))(2)Im(Mes)}Ir(CO)CNtBu (15) reacts with PhSiH3 in the dark to form the silyl compound {PhB(Ox(Me2))(2)Im(Mes)}RhH(SiH2Ph)CO (14) or {PhB(Ox(Me2))(2)Im(Mes)}IrH(SiH2Ph)CNtBu (17). These examples demonstrate the enhanced thermal reactivity of {PhB(Ox(Me2))(2)Im(Mes)}-supported iridium and rhodium carbonyl compounds in comparison to tris(oxazolinyl)borate, tris(pyrazolyl)borate, and cyclopentadienyl-supported compounds. |
