Electrosyntheses de composes carbonyles catalysees par des complexes du nickel: activation du monoxyde de carbone ou de composes acyles

摘要

The complex Ni~0bot generated from Nibpy~2+ is an efficient catalyst for the electrochemical conversion of organic halides into symmetrical or unsymmetrical ketones. Carbonylation reactions are achieved from either carbon monoxide or carbonyl metal complexes or carbon dioxide. Acylation reactions are obtained by coupling halocarbons with acid chlorides or anhydrides. All syntheses are conducted at normal pressure and room temperature at a constant current intensity in an undivided cell fitted with the sacrificial anode.
