Equilibria between alpha- and beta-agostic stabilized rotamers of secondary alkyl niobium complexes.
- Abstract:
-
The isopropyl chloro complex Tp(Me2)NbCl(i-Pr)(PhCandtbd1;CMe) (2) [Tp(Me2) = hydrotris(3,5-dimethylpyrazolyl)borate] exhibits a beta-agostic structure in the crystal. The conformation of the alkyl group is such that the agostic methyl group lies in the Calpha-Nb-Cl plane and the nonagostic one, in a wedge formed by two pyrazole rings. As observed by solution NMR spectroscopy, restricted rotation about the Nb-C bond allows the observation of an equilibrium between this species, 2beta, and a m...
