反应详情

A reaction vessel was charged with 10.0 g of (2R)-2fluorooctanol and 25 ml of pyridine, and 13.0 g of tosyl chloride was added with stirring at 0°-5° C. After the reaction was effected for 6 hours, the mixture was poured into water and extracted with 100 ml of benzene. The resultant solution in benzene was washed sequentially with water, an aqueous solution of NaHCO3 and water in that order, and dried over Glauber's salt. The solvent was distilled off to obtain 19.0 g (yield 92.6%) of crude (2R)-2-fluorooctyl tosylate as the residue.
