Preparations and Structures of 3-Chloro-ONN-4'-methylazoxybenzene and 4-Methoxy-ONN-4'-methylazoxybenzene

Article abstract of DOI:10.1246/bcsj.60.3814

A treatment of 3-chloro-NNO-4'-methylazoxybenzene (1β) with CrO3 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.
