Adding a certain compound to certain chemical reactions, such as: 67515-59-7, name is 4-Fluoro-3-(trifluoromethyl)benzonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 67515-59-7, SDS of cas: 67515-59-7
K2CO3 (2.0 eq.) and 2.0 equiv. of the corresponding nucleophile (Nu in scheme 16) were added to a solution of 4-fluoro-3-(trifluoromethyl)benzonitrile (1.0 eq.) in DMSO. The mixture was heated at 90 0C overnight. The mixture was cooled to r.t. and the solids were removed by filtration. Water was added to the filtrate and the product was precipitated, collected by filtration, washed with water and dried under vacuum.The following substances were synthesized following general procedure D for the nucleophilic aromatic substitution of 4-fluoro-3-(trifluoromethyl)-benzonitrile. The solvent system used for the purification, the yield and analytical data is given for each compound. Yield: 80%1H NMR (CDCl3) delta 7.92 (d, IH), 7.79 (m, IH), 7.33 (d, IH), 3.86 (m, 4H), 3.95 (m, 4H)
