Full Title
Heterocyclic compounds containing 1,4-diazine or hydrogenated 1,4-diazine rings > not condensed with other rings > having three double bonds between ring members or between ring members and non-ring members > with hetero atoms or with carbon atoms having three bonds to hetero atoms with at the most one bond to halogen, e.g. ester or nitrile radicals, directly attached to ring carbon atoms > Carbon atoms having three bonds to hetero atoms with at the most one bond to halogen, e.g. ester or nitrile radicals > with nitrogen atoms directly attached to ring carbon atoms > in which said hetero-bound carbon atoms have double bonds to oxygen, sulfur or nitrogen atoms > in which said hetero-bound carbon atoms are part of a substructure —C(=X)—X—C(=X)—X— in which X is an oxygen or sulfur atom or an imino radical, e.g. imidoylguanidines
