Preparation of disubstituted 1,2,5-selenadiazole N-oxides from 1,2-diketone dioximes and diselenium dichloride. Thermolysis and photolysis of 2,1,3-benzoselenadiazole N-oxide
Abstract
Reaction of 1,2-diketone dioximes with diselenium dichloride in dimethylformamide gives disubstituted 1,2,5-selenadiazole N-oxides; the thermal and photochemical behaviour of 2,1,3-benzoselenadiazole N-oxide is described.
