4,7-Dichloro[1,2,5]oxadiazolo[3,4-d]pyridazine 1-oxide
Dihalogenated derivatives of [1,2,5]chalcogenadiazolo[3,4-d]pyridazines are of interest as precursors for both photovoltaic materials and biologically active compounds. In this communication, 4,7-dichloro[1,2,5]oxadiazolo[3,4-d]pyridazine 1-oxide was prepared via the reaction of 3,6-dichloro-5-nitro...
