The dehydrogenation of the alleged hexahydro-1,2,4-triazine-3,6-dione

The dehydrogenation of the alleged hexahydro-1,2,4-triazine-3,6-dione, recently reassigned the 3-amino-2,4-imidazolidinedione structure, gives upon reaction with bromine water or sodium hypobromite bis3-(2,4-dioxoimidazolidinyl)]diazene instead of tetrahydro-1,2,4-triazine-3,6-dione as reported previously in the literature.
