potassium chlorate, sulfuric acid and ferrous sulfate as a catalytic oxidation system to oxidize the aryl substituted semicarbazide to prepareazocompounds in one phase have been described first time in this paper. Fourteen azocompounds have been synthesized in excellent yields(>90%). This method only needs cheap reagents, simple instrument and short reaction time. A possible mechanism has been suggested

An efficient and convenient solidstate reaction using Fe(N03) 3 .9H 2 O/NaHSO 4 .H 2 O to oxidize aryl-substituted semicarbazides for preparing azo compounds has been reported. Eight N-aryl-2-phenyldiazene-carboxamides have been synthesized in excellent yields at room temperature. The method is efficient and rapid.

AbstractUsing ferric chloride to oxidize aryl substituted semicarbazide for preparing azo compounds has been described for the first time in this paper. Nine azo compounds have been synthesized in a good to excellent yield (≥88%). This method only needs cheap reagents, simple instruments and a short reaction time.
