2-Chloro- or 2-methoxytropone reacts with o-phenylenediamine to give 2-(D-aminoanilino)tropone, which upon heating provides 6H-cycloheptaquinoxaline (10a).Upon acidification, 10a reversibly gives a green cation, 9a. 10a is easily converted, especially

During the attempted studies of the elimination reactions of 1,3-dimethyl-(I, R = CH3)- and 1,3-diethyl-(I, R = C2H5)-2-arylbenzimidazolines, a novel rearrangement has been observed to take place resulting in substituted amides by autoxidative ring-opening.
