2-(3,4-Difluorophenyl)oxirane Use and Manufacturing
Under nitrogen protection, 14 g (100 mmol) of 3, 4-difluorostyrene was added to tetrahydrofuran, Then, hydrogen peroxide (30percent solution, 300 mmol) was added dropwise at 20 ° C, The reaction was maintained at a temperature for 4 hours, Reaction is completed, Water was added to the reaction solution, Layered, organic layer washed, Concentrated under reduced pressure, Column chromatography gave 7.3 g of 2- (3, 4-difluorophenyl) oxirane, Yield was 46.7percent and ee was only 19.43percent.
