Synthese et reduction electrochimique de sels de p-nitrophenoxy alkyl ammonium en milieu non aqueux

Abstract

Quaternary p-nitrophenoxy alkyl ammonium salts were synthesized and their electrochemical behaviour studied. The title compounds include in their molecule a hydrocarbon chain of various lengths. An activation effect provides the cleavage of the CO bond in the hydroxylamine molecule. Such a reduction step which commonly occurs at very cathodic potentials, beyond supporting electrolytes, is favoured in our case by a solvation phenomenon between the trimethylammonium group and the hydroxylamine.
