Daniel Bojer, Ajay Venugopal, Beate Neumann, Hans-Georg Stammler, and Norbert W. Mitzel* Base-induced reduction of samarium(III) and simultaneous C–H activation occurs in the reaction of the cyclic triamine 1,3,5-tricyclohexyl-1,3,5-triazacyclohexane (TCyTAC) with [SmIII(AlMe4)3]. The resulting reduction to [(TCyTAC)2SmII(AlMe4)2] is driven by oxidation of aluminum-bound methyl groups to give ethane, and it occurs in complete absence of stabilizing Cp-type systems. The C–H activation leads to a unique methinide (CH3–) species [(TCyTAC)Sm{CH(AlMe3)3}] with a five-coordinate carbon atom bound to one samarium and three aluminum atoms, which is accompanied by methane generation.
