The 18e saturated rhodium(III) species [Rh(H)(X)(κ2-NSitBu2)(bipyMe2)] (NSitBu2={4-methylpyridine-2-yloxy}ditertbutylsilyl; bipyMe2=4,4'-dimethylbipyridine) (X=Cl, 1; OTf, 2) have been prepared and characterized by NMR spectroscopy in the case of 2 it has possible to determine its solid-state structure X-ray diffraction. Complex 1 proven be an effective catalyst precursor for reaction styrene derivatives with hydrosilanes CD2Cl2. However, under catalytic conditions complex decomposes. performance 1-catalyzed strongly depends on nature silane, best was achieved using HSiMe2Ph. Theoretical 1H studies indicate that hemilabile NSi ligand is key understanding activity compound 1.
