Adding a certain compound to certain chemical reactions, such as: 57381-51-8, name is 4-Chloro-2-fluorobenzonitrile, 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 57381-51-8, category: nitriles-buliding-blocks
General procedure: Two runs were set side by side. A Schlenck tube was loadedwith [RuCl2(p-cymene)]2 (7.7 mg, 0.0125 mmol, 2.5 mol%), L3 (9.8 mg, 0.025 mmol, 5 mol%),K2CO3 (173 mg, 1.25 mmol), The tube was backfilled with Ar (3 ×). Under light backflow of Ar, NMP (2.5 mL) was added, followed by the required substrate (1c-1e) (0.6 mmol), and p-chloroanisole (2a;62 L, 71 mg, 0.5 mmol). The tube was sealed and the reaction mixture was stirred at 140 C for 24hours. After cooling to room temperature, the reaction mixtures from both tubes were combined in H2O(40 mL) and EtOAc (20 mL). The organic phase was separated and washed with H2O (3 × 30 mL),dried (MgSO4), filtered, and concentrated under reduced pressure. The monoarylated products (major)were isolated after flash chromatography.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4-Chloro-2-fluorobenzonitrile, and friends who are interested can also refer to it.
