Abstract

Abstract Cyclic voltammetry and controlled-potential electrolysis were employed to study the catalytic reduction of five phenyl-conjugated haloalkynes by nickel (I) salen electrogenerated at carbon cathodes in dimethylformamide containing tetramethylammonium tetrafluoroborate. Electrocatalytic reduction of 7-bromo-and 7-iodo-1- phenyl-1-heptyne affords the carbocyclic product, benzylidenecyclohexane, in up to 41% ...
