Efficient conversion of vicinal diols to alkenes by treatment of the corresponding dimesylates with a catalytic, minimally fluorous, recoverable diaryl diselenide and sodium borohydride
In conjunction with sodium borohydride as stoichiometric reagent a catalytic quantity of bis(4-perfluorohexylphenyl) diselenide converts vicinal dimesylates to the corresponding alkenes in good yield on warming in ethanol. The diselenide is recovered in high yield by continuous fluorous extraction.
