Abstract

Abstract Published reports describe the oxidative cyclization of suitable ortho-substituted arenamines to form such products as 2, 1-benzisoxazoles, benzofurazan 1-oxides and benzotriazoles, by using bis (acetato-O) phenyliodine at room temperature. However, the reactions are often inconveniently slow. We now report attempts to achieve short reaction times with more powerful iodine (III) oxidants. These often failed to give cyclic products, ...
