Formation of Xanthone Oxime and Related Compounds Using a Combination of tert-Butyl Nitrite and Potassium Hexamethyldisilazide
摘要:
Synthesis of xanthone oxime and related compounds via nitrosation of the dibenzylic position using a combination of tert-butyl nitrite and potassium hexamethyldisilazide is described. The reaction conditions are effective for the synthesis of xanthone oxime as well as thioxanthone, acridone, and anthrone oximes, which have been difficult to synthesize from the corresponding ketones by conventional dehydrative condensation with hydroxylamine.

A simple convenient procedure of oxidative deoximation has been developed using pyridiniumfluorochromate (PFC), in combination with 30% hydrogen peroxide. The method has been found to be effective for a wide range of aliphatic and aromatic oximes, and may be used for selective cleavage of aldoximes in the presence of ketoximes.
