Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 67515-59-7, name is 4-Fluoro-3-(trifluoromethyl)benzonitrile, A new synthetic method of this compound is introduced below., Formula: C8H3F4N
General Procedure A: A solution of an appropriate substituted benzaldehyde (1.65 g, 10.86 mmol) and aryl fluoride (10.26 mmol) in DMF (15 ml_) was treated with K2CO3 (2.83 g, 21.72 mmol), and the mixture was heated in an oil bath at 80 0C for 12 h. The reaction was cooled to RT and partitioned between EtOAc and H2O. The organic phase was washed with water (3x), dried over Na2SO4 and concentrated in vacuo. Silica gel chromtagraphy (EtOAc/hexanes) afforded the pure product.Example 1; 4-r4-(2,4-Dioxo-thiazolidin-5-ylidenemethyl)-2-methoxy-phenoxy1-3- trifluoromethvl-benzonitrileA. 4-(4-Formyl-2-methoxy-phenoxy)-3-trifluoromethyl-benzonitrile was prepared from vanillin and 4-fluoro-3-trifluoromethylbenzonitrile following General Procedure A. 1H NMR (400 Hz, CDCI3) ?10.00 (s, 1 H), 8.00 (m, 1 H), 7.68 (dd, 1 H), 7.58-7.53 (m, 2H), 7.29 (d, 1 H), 6.75 (d, 1 H), 3.83 (s, 3H); LC/MS (m/z) [M+1]+ 322.1 (calculated for CI6HH F3NO3, 322.06).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
