Abstract: | The reaction of benzil 1-ureidoethylidenehydrazones 8 with a mixture of triphenylphosphine, carbon tetrachloride, and triethylamine provides a general route to 7H-imidazo1,2-b]1,2,4]triazoles 18 via the thermal reaction of the expected ketoazine carbodiimide intermediates 13 , and the structure of 18 was confirmed by X-ray crystallographic analysis. |
