Copper(I)-Catalyzed Conjugate Addition of Vinylzirconocene and Vinylzincate Reagents.

Hydrozirconation/Transmetalation with Zinc Negishi [ J. Am. Chem. Soc. 1978, 100, 2254-2256 ] Wipf [ Tetrahedron Lett. 1994, 35, 5197-5200 ] Walsh [ J. Am. Chem. Soc. 2004, 126, 6538-6539 ]

First Attempts 1,2-addition product is circumvented. 1,4-addition rate of vinylzincate is faster than vinylzirconocene.
