[GRAPHIC]An easily accessible ionic liquid, 1-methyl-3-pentylimidazolium fluoroborate, [pmIm]BF4, has been demonstrated to be an efficient catalyst as well as reaction medium for the stereoselective debromination of a variety of structurally diverse vicinal-dibromides to the corresponding (E)-alkenes in high yields under microwave irradiation. This reaction does not require any organic solvent and any metal or any conventional reducing agent, and the ionic liquid is recycled without any appreciable loss of its catalytic efficiency.

1,3-Diaryl-3-thioglycolic acid-1-propanones 3a-k have been synthesized by the reaction of either erythro-2,3-dibromo-1,3-diaryl-1-propanones 1a-k or their corresponding trans-chalcones 2(a-k) with disodio-thioglycolate in absolute ethanol. The structure of the products was proven by UV, IR, NMR spectra and elemental analysis. A reaction mechanism leading to the products, and the carbon-sulfur bond fission in alkaline medium were discussed.
