Benzofuroxan (1) reacts with phosphorus ylide 2 to give benzimidazole derivatives 8 and 10, whereas reaction of 1 with ylide 12 furnishes quinoxaline 17 via an initial Wittig-type reaction.Similarly the reaction between the furoxanoquinoxalines 19a or 19b and the ylide 2 yielded compounds 22a and 22b, respectively.In these reactions as well as in the reactions of the above furoxans with other phosphorus ylides, a significant deoxygenation of the furoxans to furazans with subsequent oxidation of the ylides is generally observed.
