Selenium Heterocycles. XXXVII. Synthesis of 4-(Thiazol-4-yl)-1,2,3-selenadiazoles and 4-(Selenazol-4-yl)-1,2,3-selenadiazoles

Starting from readily available 2-substituted-4-formylthiazoles and selenazoles, a series of 4-(2-aryl-4-selenazolyl)-1,2,3-selenadiazoles I and 4-(2-substituted-4-thiazolyl)-1,2,3-selenadiazoles II were prepared.Pyrolysis of compound II afforded (2-substituted-4-thiazolyl) acetylenes VII.Addition of potassium hydroxide pellets to an alcoholic solution of II gave 2-substituted-1,4-diselenafulvenes VIII.Decomposition of compound II with base followed by the addition of carbon disulfide gave 5-substituted 2-thioxo-1,3-thiaselenoles XI.
