Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1953-99-7, name is 3,4,5,6-Tetrachlorobenzene-1,2-dicarbonitrile, This compound has unique chemical properties. The synthetic route is as follows., category: nitriles-buliding-blocks
Into a boiling solution of 0.2 g of lithium in 50 mL of anhydrous 1-hexanol was added 1.0 g (2.6 mmol) of compound 3, 0.70 g (2.6 mmol) of compound 4, the mixture was maintained for 4 h, 1.4 g (2.0 mmol) of complex 1 was added, and the mixture was maintained for 2 h more. The solvent was distilled off, the reaction mass was dispersed in 50 mL of 10percent solution of acetic cid in acetone, the precipitate was filtered off, washed with 20 mL of 10percent ammonia solution, 100 mL of acetonitrile, 50 mL of water, and dried. Complexes 5?7 were treated with dichloromethane in a Soxhlet extractor, the extract was chromatographed on a column packed with silica gel Kieselgel 60 (Merck) (eluent dichloromethane?THF, 50 : 1 v/v). There with the mixture divided in three zones containing complexes 5?7 respectively. The complexes are dark-green powders well soluble in toluene, chloroform, dichloromethane, sparingly soluble in acetone, DMF.
According to the analysis of related databases, 1953-99-7, the application of this compound in the production field has become more and more popular.
