Titel:

A New Manganese (III) Schiff Base Complex as a Milad and Efficient Catalyst for Oxidation of Benzylic Alcohols

Absteract:

The oxidation of alcohols to carbonyl compounds is one of the most important and fundamental reactions in synthetic organic chemistry [1]. Transition metal salen complexes recognized as powerful homogeneous catalysts in the oxidation reactions by various single oxygen atom donors such as NaClO, PhIO, KHSO5, H2O2, and NaIO4 [2-3]. A number of methods are known for alcohol oxidation, until recently the traditional oxidation reactions have been performed with classic reagents such as persulfate and dichromate salts [4]. These reagents are moderately expensive, toxic, corrosive, instable, no selectivity and dangerous procedure for preparation, over oxidation to carboxylic acids and moisture- sensitive oxidants [5]. In this wok, we report the oxidation of benzylic alcohols with n-Bu4NIO4 in the presence of imidazole as axial ligand. In comparison with the data reported in the oxidation of benzylic alcohols by various reagents, our system shows the following advantages: (i) mild reaction conditions; (ii) high yields; (iii) short reaction times.
