Abstract

Using potassium chlorate, sulfuric acid and ferrous sulfate as a catalytic oxidation system to oxidize the aryl substituted carbazide to prepare new type bisazo compounds in one phase have been described for the first time in this paper. Eight bisaryl carbodiazones have been synthesized in high yields under mild conditions. A possible mechanism has been suggested.
