Nickel-catalysed electroreductive coupling of α-halogenoesters with aryl or vinyl halides

Abstract
β, γ-Unsaturated esters are obtained in moderate to good yields by a one-step electrochemical procedure from α-chloroesters and aryl or vinyl halides; a sacrificial aluminium anode, dimethylformamide as solvent, and a catalytic amount of nickel bromide-2,2′-bipyridine complex are used.
