Pentylidenecyclopentane can be conveniently prepared in up to 86% yield via the catalyticreduction of 1-iodo- or 1-bromo-5-decyne by [[2,2‘-[1,2-ethanediylbis(nitrilomethylidyne)]bis[phenolato]]-N,N‘,O,O‘]nickelate(I) electrogenerated at a carbon cathode in dimethylformamide containing tetramethylammonium tetrafluoroborate. This electrosynthesis can be accomplished at potentials for which the haloalkynes
