  可见光氧化还原催化β-硝基烯烃的金属自由基三氟甲基化

  摘要：

  在现代科学中，催化基团相互转化的方法非常重要。在这里，我们报道了在室温下硝基烯烃向高度立体选择性的1-三氟甲基烯烃的有效催化转化。这种前所未有的无金属光催化策略非常简单，并且可以使用市售CF 3光源在可见光照射下运行。

  日期：——

  An efficient method for the copper-catalyzed trifluoromethylation of terminal alkenes with an electrophilic trifluoromethylating reagent has been developed. The reactions proceeded smoothly to give trifluoromethylated alkenes in good to excellent yields. The results provided a versatile approach for the construction of Cvinyl-CF3 bonds without using prefunctionalized substrates.

  photoredox-catalyzed hydrotrifluoromethylation of unsaturated systems under continuous flow. This metal-free method is easily broadened to other perfluoroalkyl groups (RF = CF3, CFCl2, CF2Br, C4F9) thanks to the use of sulfilimino iminiums as sources of ·RF radicals. The mild reaction conditions are compatible with unactivated alkenes bearing a wide range of functionalities, as well as with alkynes for the

  我们在此报告了一种在连续流动下的不饱和系统的新型光氧化还原催化氢三氟甲基化。由于使用硫亚胺鎓作为·RF 自由基的来源，这种无金属方法很容易扩展到其他全氟烷基（RF = CF3、CFCl2、CF2Br、C4F9）。温和的反应条件与具有广泛功能的未活化烯烃相容，并首次与炔烃相容。

  We describe the Suzuki coupling reaction of (E)-(beta-trifluoromethyl)vinyldiphenylsulfonium salts with arylboronic acid. The highly efficient and selective reaction provides a useful and mild method for the synthesis of trifluoromethylated alkenes and dienes. Subsequent DFT studies showed that the oxidative addition transition state of the vinyl CS bond is much more favorable (11.7 kcal?mol1) than

• Julia–Kocienski approach to trifluoromethyl-substituted alkenes

  日期：2013.11

  A Julia-Kocienski approach to trifluoromethyl-substituted alkenes was evaluated in the reactions of 1,3-benzothiazol-2-yl, 1-phenyl-1H-tetrazol-5-yl, and 1-tbutyl-1H-tetrazol-5-yl 2,2,2-trifluoroethyl sulfones with aldehydes. Among the various conditions tested, the best yields were obtained with 1-phenyl-1H-tetrazol-5-yl 2,2,2-trifluoroethyl sulfone, in CsF-mediated, room temperature olefinations in DMSO. Aromatic aldehydes gave (trifluoromethyl)vinyl derivatives in 23-86% yields, with generally moderate stereoselectivity. Straightforward synthesis of the Julia-Kocienski reagent, and conversion to trifluoromethyl-substituted alkenes under mild reaction conditions, are the advantages of this approach.
