Benzo-as-triazine tri-N-oxides have been formed from the reaction of nitrile oxides with benzofurazan N-oxides and the structure of one derivative has been confirmed by an X-ray crystal structure analysis.

The reaction of benzofurazan N-oxides with nitrile oxides in refluxing dichloromethane affords the mono- and bis-adducts to the benzene ring, as well as benzo-as-triazine tri-N-oxides.The site-, regio-, and stereo-selectivity of the cycloadditions, the influenece of substitutents, and the isomeric composition of the isolated mono- and bis-adducts are discussed, and compared with the results of the cycloadditions to the corresponding benzofurazans.
