Abstract

Representative allylic chlorides have been coupled in excellent yields by nkkcl carbonyl in methanol as solvent. The dienc hydracarbons produced are richer in straight-chain (terminally coupled) product than those generally produced by metal coupling reactions, but isomeric allylic chlorides yield identical mixtures of isomeric dienes. The experimental facts indicate that the mechankrn of the nickel carbonyl coupling reaction may involve free allyl ...
