This work describes the employment of discrete “AgCF3” complexes as efficient transmetalating agents to PdII to surmount overlooked challenges related to the transmetalation step in Pd‐catalyzed trifluoromethylation processes. We report the participation of a unique silver ate (Cs)[Ag(CF3)2] complex, under stoichiometric and catalytic conditions, in the unprecedented one‐pot formation of PhCF3 using
这项工作描述了使用离散的“ AgCF 3 ”配合物作为Pd II的有效重金属化剂,以克服与Pd催化的三氟甲基化过程中的重金属化步骤有关的被忽视的挑战。我们报道了在化学计量和催化条件下,独特的银酸盐(Cs)[Ag(CF 3)2 ]络合物参与了以PhI为起始原料的PhCF 3的空前单锅形成。此外,我们表明,在这些转变中通常忽略的重金属化步骤也可以确定偶联过程的成功或失败。
