A Simple and Efficient Oxidant Pd(OAc)2 Catalyzed Selective Oxidation of Alkyl/Benzyl Alcohols in Presence of Air Using Recyclable Room-Temperature Ionic Liquid (RTIL)

1,3,5-Trimethyl pyrazolium tetrafluoroborate room-temperature ionic liquid was prepared and employed for the selective oxidation of alkyl/benzyl alcohols using palladium acetate by stirring at room-temperature in presence of air (oxygen from air). This green procedure gave products in moderate to good yields. Moreover, the synthesized 1,3,5- trimethylpyrazolium tetrafluoroborate ionic liquid could be recycled for at least three runs without the loss of significant activity.
