A mild and highly efficient, environmentally friendly procedure has been developed for the conversion from benzofurazan-N-oxides to quinoxaline di-N-oxides in the presence of-cyclodextrin in water at room temperature with excellent yields. The application of cyclodextrin precludes the use of organic solvent, and the catalyst can be recovered and reused in subsequent reactions with the same catalytic activity. Herein, the Beirut reaction is carried out in the medium of water for the first time. The reaction mechanism was proposed based on the inclusion complexation of-cyclodextrin with benzofurazan-N-oxides which was confirmed by 1H NMR, ultraviolet/visible spectrum, and infrared spectroscopy.

A new efficient route for the formation of quinoxaline N-oxides and N,N′-dioxides using HOF·CH3CN
Carmeli, Mira,Rozen, Shlomo
, p. 5761 - 5765 (2007/10/03)
HOF·CH3CN, a very efficient oxygen-transfer agent made readily from fluorine and aqueous acetonitrile, was reacted with various quinoxaline derivatives to give the corresponding mono N-oxides and especially the N,N′-dioxides in very good yields under mild conditions and short reaction times.
