Abstract
A new method for the phosphorylation of benzo-1,3-azoles (benzoxazole, benzothiazole, and 3-methylindole) with diethyl phosphite by electrocatalytic oxidation was proposed. The process occurs under electrochemical mild conditions (room temperature, normal pressure) in the presence of silver salts or silver oxide. This method allows one to obtain 2-phosphorylated products of benzo-1,3-azoles in good yield (up to 75%).
