Dioximes, vicinal, oxidation

Nitrogen-Oxygen Bond Formation The anodic oxidation of vicinal dioximes gives 3,4-diphenylfurazan-2-oxide by intramolecular ring formation (Scheme 42) [59]. [Pg.355]

Formation of the Nitrogen-Oxygen Bond 3.5.1 Oxidation of Vicinal Dioximes... [Pg.132]

In 1978 we reported the first anodic oxidation of benzyldioxime which afforded 3,4-diphenylfuroxan in good yield [125]. Chemical oxidation of vicinal dioximes... [Pg.132]

Jugelt et al. [136] studied the regioselectivity of the anodic oxidation of anti-98 and amphi-99 vicinal dioximes on the structure of furoxanes obtained after anodic oxidation under constant current. The furoxanes (101,102) were obtained in 22-65% yield but the ratio of the isomeric furoxane was dependent on the structure of the substrate (Scheme 54). [Pg.134]
