We report the first practical use of SF6 as a fluorinating reagent in organic synthesis. Photoredox catalysis enables the in situ conversion of SF6, an inert gas, into an active fluorinating species by using visible light. Under these conditions, deoxyfluorination of allylic alcohols is effected with high chemoselectivity and is tolerant of a wide range of functional groups. Application of the methodology
我们报道了SF 6作为有机合成中的氟化试剂的首次实际应用。光氧化还原催化能够通过使用可见光将惰性气体SF 6原位转化为活性氟化物。在这些条件下,烯丙基醇的脱氧氟化具有高的化学选择性,并能耐受多种官能团。该方法在连续流式装置中的应用可实现与分批式装置相当的产量,同时大大提高了有价值的氟代烯丙基氟化物产品的材料通量。
