Herein, we synthesized and characterized a binuclear copper(I) complex supported by the indolyl-based ligand. Employing this complex as catalyst, we have developed a three-component intermolecular trifluoromethylazolation of alkenes to deliver various trifluoromethylated azole derivatives. The method features exclusive chemo- and regioselectivity, a broad scope of alkenes and oxazoles, thiazoles, and good tolerance of functional groups under mild conditions. Preliminary mechanistic studies support a radical process for the transformation.

吲哚基铜 (I) 络合物催化烯烃的自由基过程分子间三氟甲基唑化反应

在此，我们合成并表征了一种由基于吲哚基的配体支持的双核铜 (I) 络合物。使用这种络合物作为催化剂，我们开发了一种烯烃的三组分分子间三氟甲基唑化反应，以提供各种三氟甲基化唑类衍生物。该方法具有独特的化学选择性和区域选择性，广泛的烯烃和恶唑、噻唑范围，以及在温和条件下对官能团具有良好的耐受性。初步的机理研究支持一个激进的转变过程。
