Abstract

Abstract Cyclobutanone reacts with diphenyl-1, 2, 4, 5-tetrazine, in alcoholic base and in diethylamine, to give 3, 8-diphenyl-6, 7-dihydro-1, 2-diazocin-4 (5H)-one (5) and 4- diethylamino-3, 8-diphenyl-6, 7-dihydro-1, 2-diazocine (8) respectively. With diethylamine the tetrazine yields 3, 6-diphenylpyridazine.
