Title
(EN) ELECTROCHEMICAL SYNTHESIS OF DIARYLIODONIUM SALTS
(FR) SYNTHESE ELECTROCHIMIQUE DE SELS DE DIARYLIODONIUM
Abstract
(EN) Electrochemical process for preparing diaryliodonium salts using a single compartment and a carbon anode. The process has high current efficiency and, optionally, increased para, para' regioselectivity. The process proceeds in the presence of a solvent such as acetic acid and an electrolyte such as a compound of fluorine or sulfuric acid.
(FR) Procédé électrochimique de préparation de sels de diaryliodonium en utilisant un seul compartiment et une anode en carbone. Le procédé possède une grande efficacité en utilisation du courant et, éventuellement, une meilleure para, para' régiosélectivité. Le procédé s'effectue en présence d'un solvant tel que l'acide acétique et d'un électrolyte tel qu'un composé de fluor ou de l'acide sulfurique.
