Trichloroisocyanuric acid has been recognized as a mild and efficient oxidant for both liquid-liquid and solid-liquid biphasic phase transfer catalytic epoxidation of enone, and selective oxidation of alcohols to aldehydes and ketones without any catalyst under non-aqueous condition.Initial experiment showed clearly that trichloroisocyanuric acid is a good oxidant for liquid-liquid biphasic phase transfer catalytic epoxidation of enone in the presence of inorganic base and phase transfer catalyst. The condi...
