On the Reduction of 1,3-Thiazinium Salts; Synthesis of 6,6′-Bi-1,3-Thiazinyls and 6,6′-Bi-1,3-Thiazinylidenes1,3-Thiazinium perchlorates 1 are linked together in a reaction with zinc powder or at a cathode forming 6,6′-bi-1,3-thiazinyls 3. This reaction proceeds via radical intermediates 2. Evidence of the existence of the very short-lived radicals is given by means of ring-disk-voltammogrammes as well as by electrochemical luminescence excitation. The 6,6′-bi-1,3-thiazinyls 3 undergo the reverse fission at a platinum anode resulting in thiazinium salts 1, whereas the dehydrogenation by chloranile yields the violet 6,6′-bi-1,3-thiazinylidenes 6.
