Adding a certain compound to certain chemical reactions, such as: 1077-01-6, name is 1-Fluoro-3-(trifluoromethoxy)benzene, belongs to ethers-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 1077-01-6, Recommanded Product: 1-Fluoro-3-(trifluoromethoxy)benzene
To the solution of 3- (trifluoromethoxy)fluorobenzen(1g, 5.5 mmol) in lOmL THF at -78C, n-BuLi (1.6M, 3.75mL) was added dropwise. The resulting solution was stirred at -78C for 30 min. 12 (2.1g, 8.25 mmol) in THF (5mL) was added. The mixture was warmed to room temperature and then quenched with Na2C03 in saturated Na2S203 (1: 10) (30mL). The crude product was extracted with ether. The ether layer was dried over Na2S04 and filtered through a short silica gel column to give the desired iodide as an oil. ¹H NMR (CDC13): 7.39 (m, 1H), 7.12 (d, J=9.0 Hz, 1H), 7.05 (t, J=6.0 Hz, 1H) MS (ESI): m/e 307 (M+1)+
