Abstract: An efficient catalytic system salen-Mn(III)/NBS for oxidation of secondary alcohols to ketones by inexpensive and readily available oxidizing agent NaOCl has been developed. The process resulted in good to excellent yields under the action of 2 mol % of salen-Mn(III) and 13 mol % of NBS at room temperature. However, such system was not efficient in oxidation of secondary benzyl alcohols with a strong electronicdonating substituent attached to the benzene ring due to bromination of the alcohols.

TL;DR: [Imim-TEMPO][X] (X= FeCl4, CuCl2) has been proved to be efficient and recyclable catalysts with modest or excellent yields and selectivity.
Abstract: Protocols of aerobic oxidation of secondary alcohols to ketones by using TEMPO modified by bifunctionalized imidazolium-based ionic liquids have been developed. [Imim-TEMPO][X] (X= FeCl4, CuCl2) has been proved to be efficient and recyclable catalysts with modest or excellent yields and selectivity. Therefore, relevant literatures are summarized herein.
