Friedrichsen, Willy published the artcileReactions of mesoionic five-membered heterocycles with o-quinonoid compounds. IV. Mono- and tricyclic 1,3-thiazolium-4-olates, 1,3-dithiolylium-4-olates, Related Products of catalysis-chemistry, the publication is Zeitschrift fuer Naturforschung, Teil B: Anorganische Chemie, Organische Chemie (1981), 36B(5), 609-21, database is CAplus.
Monocyclic 1,3-thiazolium-4-olates I (R = H, NO2; R1 = Ph, p-ClC6H4) react with o-quinonoid compounds to give [¦Ð4 + ¦Ð4]cycloadducts II and III; tricyclic 1,3-thiazolium-4-olates IV (X = CH:CH, S) similarly yield compounds V (Z = O, PhSO2N), which can formally be derived from a ketene tautomer. 1,3-Dithiolylium-4-olates are borderline cases; both [¦Ð4 + ¦Ð2], e.g., VI, and [¦Ð4 + ¦Ð4]adducts VII were obtained.
