Synthesis of new rhodacyanines analogous to MKT-077 under microwave irradiation
We report here a synthesis of a new rhodacyanines 7X analogous to MKT-077 with quantitative yield using as starting material the thiazolinethione 1. Merocyanines 4 and their tosylates 5 have been prepared as intermediates for this class of compounds. The reactions leading to rhodacyanine 7X have been studied under microwave irradiation.

Chemical and electrochemical investigations on thiazolium salts: A route to powerful donors in the dithiadiazafulvalene series
Thiazolium salts have been investigated, chemically and electrochemically, in order to access to the redox properties of dithiadiazafulvalenes (DTDAF). As these donor molecules are oxygen-sensitive, it is more advisable to isolate them in their oxidized f

The reaction of 3-methylthiazolium derivatives with superoxide
3-Methylbenzothiazolium salts were allowed to react with superoxide to afford dimeric bis[o-(N-formyl-N-methylamino)phenyl]disulfides and 3-methyl-2-benzothiazolones. The reaction was applied to monocyclic thiazolium salts, and novel ten-membered ring com
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.
