and functional materials, owing to its unique properties such as electron‐withdrawing character, metabolic stability, and lipophilicity. Described herein is the PhI(OAc)2‐mediated radical trifluoromethylation of vinyl azides with Me3SiCF3 to efficiently generate α‐trifluoromethyl azines. The resulting α‐trifluoromethyl azines were successfully transformed to valuable fluorine‐containing molecules such
含氟有机基序由于其独特的特性,例如吸电子特性,代谢稳定性和亲脂性,在制药,农用化学品和功能材料中正变得尤为重要。本文描述的是用Me 3 SiCF 3进行的叠氮化物的PhI(OAc)2介导的自由基三氟甲基化反应,可有效地生成α-三氟甲基嗪。所得的α-三氟甲基嗪已成功转化为有价值的含氟分子,例如α-三氟甲基酮,β-三氟甲基胺,5-氟吡唑和三氟乙基异喹啉。
