Title: Nitrile coordination to rhodium does not lead to C—H activation

Abstract

Tris(pyrazolyl)borate complexes of rhodium are well known to activate C—H bonds. The reactive [Tp′Rh(PMe 3)] fragment [Tp′ is tris(3,5-dimethylpyrazol-1-yl)hydroborate] is found to react with valeronitrile to give the κ 1N-bound complex (pentanenitrile-κN)(trimethylphosphane-κP)[tris(3,5-dimethylimidazol-1-yl)hydroborato-κ 2N 2,N 2′]rhodium(I), [Rh(C 15H 22BN 6)(C 5H 9N)(C 3H 9P)]. In contrast to the widespread evidence for the reaction of this fragment with C—H bondsviaoxidative addition, no evidence for such a complex is observed.
