摘要：

Reaction of Tp*NbCl2(PhC equivalent to CR) (R = CH3, Ph) with 1 equiv of allyl Grignard gives I moderate yield of five-membered niobacycles Tp*(Cl)Nb[C(Ph)C(R)CHCH(CH3)] resulting from an allyl-alkyne coupling reaction accompanied by a 1,3-hydrogen shift in the allyl moiety. Both the spectroscopic and X-ray crystal data indicate an eta(4)-butadienyl formulation is appropriate for the new ligand.
