Abstract:2-Fluoroanisole was synthesized from o-difluorobenzene and sodium methoxide by one-step etherification in toluene and tetrahydrofuran. The structure of the compound was characterized by 1H NMR. The effect of raw material ratio, reaction temperature and solvent on the yield of target product was investigated. Under the optimized conditions, the yield of target product was of 84.8%. The process is simple, high yield, environment-friendly and suitable for industrial production. |
Key words:o-difluorobenzene; one-step etherification; 2-fluorobenzoether |
