each case more than 98% of the Markovnikov products and <2% of the regioisomers in good yield. The formal addition of methanesulfenyl fluoride with the combination of dimethyl(methylthio)sulfonium fluoroborate (DMTSF) and Et3N·3HF gave a 94:6 mixture of both regioisomers. Only small phenylsulfenyl fluorination of methallyl chloride has been observed when treated with N-phenylthiophthalimide (NPTP) and
使用N-卤代琥珀酰亚胺与三乙胺三氢氟化物(Et 3 N·3HF)结合进行甲基甲酰氯的卤代氟化反应,在每种情况下,收率均超过98%的马尔可夫尼科夫产物和<2%的区域异构体。甲硫基氟化物与氟硼酸二甲基(甲硫基)and(DMTSF)和Et 3 N·3HF的组合形式正式加成,得到两种区域异构体的94:6混合物。用N-苯基硫代邻苯二甲酰亚胺(NPTP)和Olah's试剂处理时,仅观察到甲烯丙基氯的少量苯硫基氟化。与苯亚磺酰氯一起生成1,3-二氯-2-甲基-2-(苯硫基)丙烷,将其在0°C下用Olah试剂或Et 3处理N·3HF在60°C下重排为1,2-二氯-2-甲基-2-(苯硫基)丙烷。在-30°C下用氟化银在二氯甲烷中处理1,3-二氯-2-甲基-2-(苯硫基)丙烷,得到1-氯-2-氟-2-甲基-3-(苯硫基)丙烷,其为也通过1-溴-3-氯-2-氟-2-甲基丙烷与硫酚盐的反应获得。
