These Cp*­(iPr2MeP)­Fe­(H)­SiHR (R = DMP, Trip) complexes are in equilibrium with the corresponding iron silyl complexes, Cp*­(iPr2MeP)­FeSiH2R, which can be trapped and characterized for R = Trip. Unlike the Ru analogues, the Fe silylene complex with R = DMP is observed to undergo an intramolecular CH activation involving formal addition of a benzylic CH bond across the FeSi bond. This increased activity for bond activations is also observed for reactions with hydrogen, where Fe reacts faster than a Ru analog to form the hydrogenation product, Cp*­(iPr2MeP)­H2FeSiH2DMP. %I ACS Publications
