Electrochemical reduction of N-thioamidoimidates: application to the synthesis of thiazolo[5,4-d]thiazoles

---

Résumé

The reduction of N-thioamidoimidates (1) has been examined in aprotic media at a mercury electrode. As shown by cyclic voltammetry at fast scan rates and controlled potential electrolysis, an overall irreversible one electron transfer is followed by a rapid second order chemical reaction leading to a dimer which involves to thiazolo [5, 4-d] thiazole by intramolecular cyclization.
