title: A new efficient route for the formation of quinoxaline N-oxides and N,N'-dioxides using HOF.CH3CN.
abstract: 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.
