Mono- and difluorinations of sulfides were achieved using a novel fluorinating reagent, IF5–Et3N–3HF. The reagent is applicable for substrates having various electron-withdrawing groups, such as an ester, amide, ketone, nitrile, sulfone, or trifluoromethyl. Because more than one fluorine atom on IF5 is used, a large excess amount of the reagent is not necessary, even for the difluorination reaction.
利用新型氟化试剂 IF5-Et3N-3HF 实现了硫化物的单氟化和二氟化。该试剂适用于具有各种夺电子基团的底物,如酯、酰胺、酮、腈、砜或三氟甲基。由于 IF5 上使用了一个以上的氟原子,因此即使进行二氟化反应,也无需过量使用该试剂。
