C-H and C-C agostic interactions in cycloalkyl tris(pyrazolyl)boratoniobium complexes
Cycloalkyl niobium complexes, TpMe2NbX(R)(MeC≡CMe) (TpMe2 = hydrotris(3,5-dimethylpyrazolyl)borate; X=Cl, R = c-C3H5 (2a); X = Br, R = c-C3H5 (2b), X = Cl, R = c-C5H9 (3), X = Cl, R = c-C6H11 (4),) have been prepared from TpMe2NbCl2(MeC≡CMe). The cyclopropyl complex 2a shows no sign of C-H agostic i...
