摘要：

Treatment of 1-tributylstannylalkynes with Cp2Zr(H)Cl affords olefinic intermediates substituted by both Bu3Sn and Cp2ZrCl groups on the terminal sp2-like carbon. These stereodefined reagents can be selectively transmetalated at zirconium to afford cuprates which deliver product vinyl stannanes in both substitution and Michael addition reactions.
