Abstract

Procedure for obtaining new dioxo-hydropyridazines, especially 1-aryl-4 or 5-halogen-3,6-dioxo-1,2,3,6-tetrahydro- and 1-aryl-4,5-dihalogen-3, 6-dioxo-1,2,3,4,5,6-hexahydro-pyridazines, characterized in that in the double bond 4.5 of them 1-aryl-3,6-dioxo-1,2,3,6- tetrahydro-pyridazines, which in position 2 show a low aliphatic hydrocarbon residue, halogen is attached and, if desired, 1-aryl-4,5-dihalogen-3,6-dioxo-1,2,3,4, 5,6-hexahydro-pyridacines obtained, which in at least one of positions 4 and 5 show a hydrogen atom and in position 2 contain a low aliphatic hydrocarbon residue, are treated with halogen-hydrogen dissociating agents or in 1- 2-unsubstituted aryl-4 or 5-halogeno-3,6-dioxo-1,2,3,6-tetrahydropyridacines, position 2, a low aliphatic hydrocarbon radical, and, if appropriate, the compounds obtained with rest are introduced unsubstituted aryl this is nitrated and if desired, in the 1-nitroaryl compounds or taken, the nitric group is reduced to amine group.
