A method for the synthesis of derivatives of 5(or 4)-hydrazinoimidazole-4-(or 5)-carboxylic acid by reducing the corresponding diazoimidazoles with stannous chloride has been developed, and a number of hydrazones and semicarbazides have been synthesized.I

Cyclization of azo compounds, synthesized 5-diazoimidazoles and 2-naphthol or p-substituted phenols, into naphth[2,1-e]imidazo[5,1-c]-1,2,4-triazines and benz[e]imidazo[5,1-c]-1,2,4-triazines occurs only in the presence of p-toluenesulfonic acid. Imidazo[4,5-d]-1,2,3-triazines are also formed in this reaction when an amide substituent is present in the imidazole ring.
