An adduct, 3,4-dicyano-1,6-dimethyl-2,5-diaza-7,8-dioxabicyclo[4.2.1]non-3-ene, was obtained from 2,3-dicyano-5,7-dimethyl-6H-1,4-diazepine and hydrogen peroxide in the presence of alkali or a tertiary amine. It was dehydrogenated by iodobenzene diacetate into 3,4-dicyano-1,6-dimethyl-2,5-diaza-7,8-dioxabicyclo[4.2.1]nona-2,4-diene; further oxidation by m-chloroperbenzoic acid gave 4,5-dicyano-1,8-dimethyl-2,7-diaza-3,6,9,10-tetraoxatetracyclo[,405,7]undecane.
