Abstract:
Transition metal–alkane complexes—termed σ-complexes because the alkane donates electron density to the metal from a σ-symmetry carbon–hydrogen (C–H) orbital—are key intermediates in catalytic C–H activation processes, yet these complexes remain tantalizingly elusive to characterization in the solid state by single-crystal x-ray diffraction techniques. Here, we report an approach to the synthesis and characterization of transition metal–alkane complexes in the solid state by a simple gas-solid reaction to produce an alkane σ-complex directly. This strategy enables the structural determination, by x-ray diffraction, of an alkane (norbornane) σ-bound to a d 8 –rhodium(I) metal center, in which the chelating alkane ligand is coordinated to the pseudosquare planar metal center through two σ-C–H bonds.
