3-溴-2-氟丙-1-烯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 11.6 g (65.5 mmol) of ethyl N-(2,2-dimethoxyethyl)-carbamate, 15 g of powdered potassium hydroxide and 0.25 g of triethylbenzylammonium chloride are initially introduced into 65 ml of toluene and 10 g (72 mmol) of 2-fluoroallyl bromide are added dropwise at room temperature. The mixture is stirred overnight at room temperature, 100 ml of water are added, and the aqueous phase is separated off and extracted using 30 ml of toluene. The organic solutions are dried over magnesium sulphate and concentrated, and the residue is distilled. are added dropwise at room temperature the aqueous phase is separated off extracted The organic solutions are dried over magnesium sulphate concentrated the residue is distilled
