The combo pack: Copper‐catalyzed trifluoromethylation of alkenes bearing an allylic proton combined with CC bond formation affords the title compounds in good to high yields (see scheme). The reactions are faster than allylic trifluoromethylation, especially in 1,4‐dioxane. A unique 1,6‐oxytrifluoromethylation occurred instead of an anticipated seven‐membered ring forming carbotrifluoromethylation
组合包:带有烯丙基质子的烯烃的铜催化三氟甲基化与CC键的形成相结合,可提供标题化合物,收率高至高(参见方案)。该反应比烯丙基三氟甲基化更快,尤其是在1,4-二恶烷中。发生了独特的1,6-氧三氟甲基化反应,而不是预期的七元环形成的碳三氟甲基化反应。
