| Abstract: | A system of paired electrosynthesis of 1,2 diol equivalents was established.H\-2O\-2 generated at cathode was catalyzed by bis(acetylacetonato)vanadyl/bis(acetylacetonato)pervanadylVO(acac)\-2/VO(acac)\-2OOH] redox mediator to convert olefin into epoxide. At anode, olefin was electrooxidized to form bromohydrin.By combining these two systems,paired electrosynthesis of 1,2 diol equivalents can be realized.In this work,maleic acid was selected as a typical starting compound.Under the optimum conditions,some other olefins were also oxidized.The cathodic epoxidation of styrene in a cosolvent system was investigated.Polystyrene supported VO(acac)\-2 was prepared and its catalytic activity was evaluated in an aqueous electrolyte. |
