Nickel-Catalyzed Cyclizations and Couplings with Vinylzirconium Reagents

Nickel-Catalyzed Cyclizations and Couplings with Vinylzirconium Reagents

1,3-Dienes were prepared by a variety of nickel-catalyzed couplings and cyclization processes. Intermolecular or partially intramolecular couplings of alkynes, vinylzirconium reagents, and either aldehydes or enones efficiently proceeded to generate a broad range of functionalized dienes.
