Oxidative desulfurization of azole-2-thiones with benzoyl peroxide: Syntheses of ionic liquids and other azolium salts

1-Alkyl-3-methylimidazole-2-thiones were prepared from amino esters in one pot and converted to inherently halide-free 1-alkyl-3-methylimidazolium benzoates by oxidation with benzoyl peroxide followed by a novel anion exchange. Also reported are the outcomes of exchanges with other anions, acidifications of the imidazolium benzoates to other salts, and extension of the method to the syntheses of 1,3-diphenylimidazolium and 3-methyl- and -butylthiazolium salts.

REACTION OF N-ALKYLTHIAZOLIUM HALIDES, INCLUDING THIAMINE, WITH SUPEROXIDE ION. CHEMISTRY AND BIOLOGICAL IMPLICATIONS.

N-alkylthiazolium halides are transformed by KO2 into the corresponding thiazolin-2-ones and thiazolin-2-thiones; the same reactions occur with thiamine, whose thiazolin-2-one pyrophosphate has been reported to be a strong inhibitor of pyruvic dehydrogenase.
