An efficient route of organoselenium-catalyzed oxidative allylic fluorination has been developed. In this transformation, bulky electrophilic fluorinating reagent N-fluoro-2,4,6-trimethylpyridinium triflate (TMFP-OTf) was employed as the oxidant and fluorine source. Notably, TEMPO as an additive affects the fluorination and leads to better substrate scope and excellent functional group tolerance. By this protocol, a variety of allylic fluorides were synthesized in good to excellent yields. The obtained allylic fluorides could be converted into vinyl fluorides efficiently in the presence of an appropriate base.

亲电子NF试剂催化有机硒催化氧化烯丙基氟化

已经开发出有机硒催化的氧化烯丙基氟化的有效途径。在该转化中，使用大体积的亲电氟化试剂三氟甲磺酸N-氟-2,4,6-三甲基吡啶鎓（TMFP-OTf）作为氧化剂和氟源。值得注意的是，TEMPO作为添加剂会影响氟化作用，并导致更好的基材范围和出色的官能团耐受性。通过该方案，合成了多种烯丙基氟化物，收率良好至极佳。在适当的碱的存在下，可以将获得的烯丙基氟化物有效地转化为氟乙烯。
