참여 물질

반응 단계

The boronic acid in an amount of 9.0 g was dissolved in 60 ml of an ether, and the solution thus formed was added dropwise with 60 ml of a 10% aqueous hydrogen peroxide while being refluxed under a heated condition. After the dropping of the aqueous hydrogen peroxide was finished, the reflux under a heated condition was further continued for 2 hours. Then, the ether layer was separated with a separating funnel, washed with water, dried, and then subjected to distillation under a reduced pressure to separate the solvent to obtain 7.1 g of 2,3-difluorophenol.
