Abstract

From 3‐methyl‐4‐furoxancarboxylic acid hydrazide and 4‐methyl‐3‐furoxancarboxylic acid hydrazide the corresponding azides have been synthesized. 3‐Methyi‐4‐furoxancarboxylic acid azide normally underwent the Curtius reaction to give the expected carbamic acid derivative. The degradation of 4‐methyl‐3‐furoxancarboxylic acid azide led to the N‐(4‐methylfuroxan‐3‐yl)‐carbamic acid derivative at low temperatures and to N‐(3‐methylfuroxan‐4‐yl)carbamic acid derivative at higher temperatures.
