Abstract

A treatment of 3-chloro-NNO-4′-methylazoxybenzene (1β) with CrO 3 in acetic acid gave 3- chloro-ONN-4′-methylazoxybenzene (1α) in good yield, whereas 4-methoxy-ONN-4′- methylazoxybenzene (2α) isomerized partially to 4-methoxy-NNO-4′-methylazoxybenzene (2β) under the same conditions. The structures of 1α and 2α have been determined by X-ray analysis.
