The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1-(2-Methylthiazol-4-yl)ethanone( cas:23002-78-0 ) is researched.Safety of 1-(2-Methylthiazol-4-yl)ethanone.Shafiee, A.; Anaraki, M.; Bazzaz, A. published the article 《Selenium heterocycles. XXXVII. Synthesis of 4-(thiazol-4-yl)-1,2,3-selenadiazoles and 4-(selenazol-4-yl)-1,2,3-selenadiazoles》 about this compound( cas:23002-78-0 ) in Journal of Heterocyclic Chemistry. Keywords: formylthiazole conversion thiazolylselnadiazole; formylselenazole conversion selenazolylselenadiazole; thiazolylselenadiazole preparation conversion diselenafulvene; thiaselenole thiazolylthioxo; carbon disulfide reaction thiazolylselenadiazole. Let’s learn more about this compound (cas:23002-78-0).
Starting from readily available 2-substituted-4-formylthiazoles and selenazoles, a series of selenazolylselenadiazoles I (R = e.g. Ph, 4-MeOC6H4, 4-BrC6H4; X = Se) and thiazolylselenadiazoles I (X = S) were prepared Pyrolysis of compound I (X = S) afforded thiazolylacetylenes II. Addition of KOH pellets to an alc. solution of I (X = S) gave diselenafulvenes III. Decomposition of compound I (X = S) with base followed by the addition of CS2 gave thiazolylthioxothiaselenoles IV.
