gem-Dichlorocyclopropanes 1 react with tetra-n-butylammonium fluoride trihydrate in DMF or with potassium fluoride and tetra-n-butylammonium hydrogen sulphate in acetonitrile/water mixture, to afford gem-difluorocyclopropanes 2, in moderate yields.
宝石-二氯环丙烷1与DMF中的四正丁基氟化铵三水合物或在乙腈/水混合物中与氟化钾和硫酸四正丁基铵在乙腈/水混合物中反应,以中等收率得到宝石-二氟环丙烷2。
