Related Products of 1835-65-0, These common heterocyclic compound, 1835-65-0, name is 3,4,5,6-Tetrafluorophthalonitrile, its 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.
A thermometer attached to a 100ml four-necked reactor, tetrafluorophthalonitrile (compound (5)) 6.0g (30mmol), potassium fluoride 21g (36mmol, 1.2 eq.) and acetonitrile into a 50ml, stirring under a 5 it cooled. Here, beta- naphthol (compound (a-1)) was added dropwise to 4.3g (30mmol, 1.0eq.). After the addition was completed, the mixture was reacted for 1 hour at less than 5, heated to room temperature and allowed to react for 2 hours. After the reaction, the reaction mixture was taken out by releasing the water, and filtering the precipitated solid. Resulting crude by well washing the product with isopropanol and dried to obtain the compound (4-1), 6.7g, as a white solid (yield 69percent).
Statistics shows that 3,4,5,6-Tetrafluorophthalonitrile is playing an increasingly important role. we look forward to future research findings about 1835-65-0.
