Synthesis of diols from 1,2-epoxy-3-butene

Activated carbon supported Co1.5PW12O40 as efficient catalyst for the production of 1, 2 cyclohexane diol by oxidation of cyclohexene with H2O2 in the presence of CO2

“…Consequently, several methods for their synthesis such as reduction of ketones and hydroxy α-diketones, hydrolysis of epoxides and oxidation of olefins have been reported (6)(7)(8)(9)(10). However, in these methods, several steps are performed, solvents and hazardous substances as oxidants such as OsO 4 /N-methylmorpholine-N-oxide, RuCl 3 / NaIO 4 , KMnO 4 and organometallic complexes have been used (9,11,12). KMnO 4 was generally used in excess and this leads to the formation of several undesirable by-products (12).…”
