Application of 1953-99-7,Some common heterocyclic compound, 1953-99-7, name is 3,4,5,6-Tetrachlorobenzene-1,2-dicarbonitrile, molecular formula is C8Cl4N2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
3,4,5,6-tetrachlorophthalonitrile (5 g), 2-isopropylphenol (2.5608 g), K2CO3 (3.898 g), and N,N-dimethylformamide (50 ml) are put in a 100 ml flask and then stirred while heated at 50¡ã C. When a reaction is complete, an extraction is performed with EA (ethyl acetate). After the extraction, a liquid column-purified through column chromatography with EA/hexane is concentrated to obtain a solid, and the solid is vacuum-dried, obtaining a compound according to Synthesis Example 6.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3,4,5,6-Tetrachlorobenzene-1,2-dicarbonitrile, its application will become more common.
