ELECTROSYNTHESE CATALYTIQUE D'ACIDES BENZOIQUES para-SUBSTITUES A PARTIR DU DERIVE HALOGENE CORRESPONDANT ET DE L'ANHYDRIDE CARBONIQUE

Article abstract of DOI:10.1016/0022-328X(84)85153-0

Electrochemical reduction of the complex formed by insertion of an electrogenerated nickel(0) atom into the carbon-halogen bond of a p-halogeno-substituted aromatic compound in the presence of CO2 leads to formation of the corresponding aromatic carboxylate.At room temperature the electrochemical synthesis needs catalytic quantities of nickel chloride coordinated to triphenylphosphine or 1,2-bis(diphenylphosphino)ethane.
