In contrast with unactivated alkenes, the corresponding hydrotrifluoromethylation of styrene has remained challenging due to the strong propensity of styrene for oligomerization and polymerization. On the basis of our newly developed trifluoromethylation reagent, TFSP, herein we present a general method for the hydrotrifluoromethylation of styrene under photoredox catalysis. The substrate scope was
与未活化的烯烃相比,由于苯乙烯具有强烈的低聚和聚合倾向,相应的苯乙烯氢三氟甲基化仍然具有挑战性。在我们新开发的三氟甲基化试剂 TFSP 的基础上,我们提出了一种在光氧化还原催化下苯乙烯氢三氟甲基化的通用方法。底物范围进一步扩展到未活化的烯烃、丙烯酸酯、丙烯酰胺和乙烯基杂原子取代的烯烃。通过相关的去质子三氟甲基化和三氟甲基三氟乙氧基化反应展示了该方法的可调性。
