C-H activation with scandium: Reaction of [Cp2*ScCH3] (1, Cp* = C5Me5) with MesSiH3 (Mes=2,4,6-C6H2Me3) yielded a new scandium silyl complex [Cp2*ScSiH2Mes] (2) by an unusual σ-bond metathesis pathway. Complex 2 activates the C-H bonds of benzene and methane. In the presence of excess Ph2SiH2, the catalytic dehydrosilation of saturated and unsaturated hydrocarbons, including methane, was accomplished, with [Cp2*ScH] (see scheme; R=CH3, C3H5, CH=CMe2) which can be formed from 1 or 2. This appears to be the first example of catalytic methane functionalization by σbond metathesis.
