Stereodefined multisubstituted 1-cyano- and 1,4-dicyano-1,3-butadiene derivatives were obtained in excellent yields of the isolated product from their corresponding monohalo-and dihalobutadienes and CuCN. This reaction proceeded with high stereose-lectivi
Cycloaddition reactions of 1-lithio-1,3-dienes with aromatic nitriles affording multiply substituted pyridines, pyrroles, and linear butadienylimines

Fully or partially substituted 1-iodo- or 1-bromo-1,3-dienes could be readily lithiated using t-BuLi or n-BuLi to afford their corresponding 1-lithio-1,3-diene derivatives in quantitative yields. When these in situ generated lithium reagents were treated
