Photolysis of pyridazine 1,2-dioxides; formation of the novel 1,4,6,7-dioxadiazocin ring system

Abstract

Irradiation of pyridazine 1,2-dioxides in dich-PHOTOCHEMICAL reactions of heterocyclic amine N-oxides, loromethane afforded 1,4,6,7-dioxadiazocins as major e.g., pyridine,l pyridazine2a#b$c and pyrimidine N-oxides,Z products, together with the deoxygenated pyridazines. have been widely investigated. Photochemical reactions of "'-dioxides of heteroaromatic compounds such as
