Abstract

A convenient route to 4-and 7-methoxybenzo [b] thiophenes has been developed in the course of electrochemical studies of these molecules. The anodic oxidations of 4-methoxy-, 5-bromo-4-methoxy-, 5-methyl-4-methoxy-, and 6-bromo-7-methoxybenzo [blthiophene, 17a- d, respectively, in methanolic potassium hydroxide at a platinum anode have been investigated. The products obtained from the oxidation of these compounds were ...
