A short and efficientsynthesis of 1-(2-oxido-1,2,5-oxadiazol-3-yl)alkyl nitrates from 3-alkyl-1,2,5-oxadiazole 2-oxides, using a mixture of nitric and sulfuric acids in chloroform, has been developed. The scope of the unconventional reaction was established; its mechanism likely included a new Grob-type fragmentation.

A versatile one-pot synthesis of 4-substituted 3-(nitrooxyalkyl)furoxans by the reaction of 3-alkylfuroxans with a mixture of nitric and sulfuricacids was developed. A plausible mechanism of this unusual transformation was explained in terms of a new Grob-type fragmentation.
