2-trifluoroethylation of acrylamides by Pd-catalyzed C–H bond activation was reported by using a fluorinated hypervalent iodine reagent as a coupling partner. At room temperature, this additive-free approach allowed the synthesis of Z-2,2,2-trifluoroethylated acrylamides (19 examples, up to 73% yield) in a stereoselective manner. Under these mild reaction conditions, the methodology turned out to be functional
通过使用氟化高价碘试剂作为偶联伙伴,报道了通过 Pd 催化的 C-H 键活化直接对丙烯酰胺进行 2,2,2-三氟乙基化。在室温下,这种无添加剂的方法允许以立体选择性方式合成Z -2,2,2-三氟乙基化丙烯酰胺(19 个例子,产率高达 73%)。在这些温和的反应条件下,该方法被证明是官能团耐受性的,机理研究让我们更好地了解了转化。
