The activation of compounds containing aliphatic C-H bonds and the transformations of these materials into functionalized organic compounds are major goals of organometallic and catalytic chemistry. Late transition metals typically react with hydrocarbons by oxidative addition of C-H bonds to low-valent, electron-rich metal centers, such as the reactive Ir(I) species Cp*IrL (Cp* = ([eta][sup 5]-C[sub 5]Me[sub 5]); L = tertiary phosphine). We now report that the more electron-deficient iridium(III) center in the trifluoromethanesulfonate (triflate) complex Cp* (PMe[sub 3])Ir (CH[sub 3]) (OTf) (1, OTf = OSO[sub 2]CF[sub 3]) reacts with several types of aliphatic C-H bonds, including that in methane, as well as with the Si-H bonds in silanes. 26 refs., 1 fig.
