[C5Me5Rh(C2H3SiMe3)2], 1, has been shown to be a catalyst for the selective addition of olefins to the ortho position of aromatic ketones. The addition of vinyltrimethylsilane to benzophenone was studied by NMR spectroscopy, which indicated that 1 was the catalyst resting state for this process. This reaction was applied to a series of olefins (allyltrimethylsilane, 1-pentene, norbornene, 2,2‘-dimethyl-3-butene

with phenanthroline‐type ligands and activated with Grignard reagents serve as inexpensive and effective catalysts for the ortho alkylation of aromaticimines with a variety of olefins (see scheme). The new catalytic systems feature remarkably mild reaction conditions for CH bond activation and functionalization.
