The exchange of chlorine in β-chloroalkyl phenyl (or methyl) thioethers by fluorine, with anchimeric assistance of sulfur, is very easily realized with the almost neutral fluorinating reagent, Et3N.3HF. The ‘one-pot’ reactions of alkenes with sulfenyl chlorides and subsequently with Et3N.3HF lead to the corresponding β-fluoroalkyl thioethers in high yields.
用几乎中性的氟化试剂Et 3 N.3HF可以很容易地实现在氟的β-氯烷基苯基(或甲基)硫醚中氯的交换,并辅以硫。烯烃与亚磺酰氯的“一锅法”反应,然后与Et 3 N.3HF的“一锅法”反应,可高产率地生成相应的β-氟代烷基硫醚。
