1,2-Diphenyl-3,5-dimethyl-4-oxo-6,7-diazabicyclohept-2-ene, a nitrogen unsubstituted diazetidine with an unusually unreactive nitrogen.

In the title ring system, the benzylic nitrogen (N7), whether substituted or not, is abnormally unreactive.Hydrolysis of the di-urethanes 3a or b occurs readily at N6 to give 10a or b, but not at all at N7.In 3d Pd-H2 remo
