英文摘要: A transition metal-free catalyst composed of N-hydroxyphthalimide (NHPI), 2,3-dichloro-5,6-dicyano-benzoquinone (DDQ), and NaNO2 was studied for the selective oxidation of alcohols using O-2 as oxidant. The reaction results showed that this catalyst system can effectively catalyze the oxidation of alcohols to the corresponding aldehydes or ketones. 99% selectivity for benzaldehyde at 65% conversion of benzyl alcohol was obtained at 80 degrees C for 6 h. In the process of reaction, DDQ abstracted a hydrogen atom from NHPI to generate a highly reactive PINO free radical and hydroquinone. Then, PINO abstracted a hydrogen atom from alcohols to generate aldehydes or ketones. Finally, NO from NaNO2 decomposition in the reaction media catalyzed the oxidation of hydroquinone to quinone by O-2.
