derivatives of 5-oximinobenzo-2,1,3-oxadiazole-4-one is reported and their rearrangement to 4,7-dioximino derivatives of benzo-2,1,3-oxadiazole, 2-phenylbenzotriazole and benzotriazole described. Geometricisomerism related to oximino group was investigated. NMR spectra of 4,7-dioximes show the existence in solution of three geometricalisomers, whose configuration was assigned. The derivatives of 5-oximinobenzo-2
