The C-X bond (X = Br, Cl) of α-haloketones is smoothly trifluoromethylated with the fluoroform-derived CuCF(3) reagent recently developed in our laboratories. This is the first nucleophilic α-trifluoromethylation reaction of carbonyl compounds and a rare example of CF(3)-C(sp(3)) coupling. The transformation employs only low-cost chemicals and cleanly occurs in up to 99% yield at room temperature,
α-卤代酮的 CX 键 (X = Br, Cl) 被我们实验室最近开发的氟仿衍生的 CuCF(3) 试剂顺利地三氟甲基化。这是羰基化合物的第一个亲核 α-三氟甲基化反应,也是 CF(3)-C(sp(3)) 偶联的罕见例子。该转化仅使用低成本化学品,并且在室温下以高达 99% 的收率干净地发生,从而为获得有价值的 2,2,2-三氟乙基酮提供了前所未有的轻松入口。
