Selenium catalysed oxidations with aqueous hydrogen peroxide. Part 3: Oxidation of carbonyl compounds under mono/bi/triphasic conditions

The total synthesis of 3,5-bis(perfluorooctyl)phenyl butylselenide (), a recyclable catalyst for oxidation reactions with hydrogen peroxide, is described. The catalyst can be used for oxidation of aldehydes and ketones under monophasic, but also fluorous biphasic or fluorous triphasic conditions.
