Abstract
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. It has been shown that under the reduction conditions selected imidazo[4,5-d]-1, 2, 3-triazinone does not have cryptodiazonium properties.
