Furazan N-oxides with a strained ring bridging the 3- and 4-positions are progressively deoxygenated by trialkyl phosphites, forming furazans, which can in some cases be isolated, and dinitriles. Heating in the presence of an acetylene forms bis(nitrile oxide) adducts (isoxazoles), with the more highly-strained types.

widely used in the field of high energy density materials because of its excellent properties such as high density, high standard enthalpy of formation and high nitrogen content. However, its existing synthesis methods are still restricted by the problems of difficult substrate preparation and manual handling of hazardous reagents. Herein, we disclosed a mildoxidation strategy to efficiently obtain
