The thermal decomposition of 5-methoxy-3-methyl-4-phenylazoisoxazole (1) was re-investigated.Cleavage in the presence of dipolarophiles gave methyl 5-methyl-2-phenyl-1,2,3-triazole-4-carboxylate (3), which derives from a known rearrangement, and N-phenylmethoxycarbonylnitrilimine, which was trapped.The mechanism of the thermal decomposition is discussed.
