応用分野 · 1 件

使用2-Acetylthiophene(2AT) is used as an intermediate in the manufacturing of drugs like Tiamonium Iodide, Suprofan, Stepronin, Tenonitrozole, Namirotene, etc. 2AT is used as an important precursor to thiophene-2-acetic acid (T2AA) or its acid chloride (Cl) and thiophene-2-carboxylic acid (T2CA) (Cl). It is important that the process used to synthesize 2AT yields the lowest amount of 3- acetylthiophene isomer.

調製方法 · 1 件

純化方法Fractionally distil the thiophene through a 12-plate column, and fraction b 77o/4mm is collected. Also wet the acetylthiophene in order to remove and free thiophene which forms an azeotrope with H2O, b 68o. Store it in a brown bottle, and the clear colourless liquid remains thus for extended periods. [Kosak & Hartough Org Synth Coll Vol III 14 1955, Hartough & Kosak J Am Chem Soc 69 3093 1947.] The red 4-nitrophenylhydrazone crystallises from EtOH with m 181-182o. [Beilstein 17/9 V 387.]
