While trifluoromethylthiolation of aryl halides has been extensively explored, the current methods require complex and/or air-sensitive catalysts. Reported here is a method employing a bench-stable Ni(II) salt and an iridium photocatalyst that can mediate the trifluoromethylthiolation of a wide range of electronically diverse aryl and heteroaryl iodides, likely via a Ni(I)/Ni(III) catalytic cycle.
虽然已经广泛探索了芳基卤化物的三氟甲基硫醇化,但目前的方法需要复杂的和/或空气敏感的催化剂。本文报道了一种使用台式 Ni(II) 盐和铱光催化剂的方法,该方法可以介导各种电子多样化芳基和杂芳基碘化物的三氟甲基硫醇化,可能通过 Ni(I)/Ni(III) 催化循环. 该反应具有广泛的官能团耐受性和在药物化学中的应用潜力,如获得(外消旋)-莫奈太尔的后期功能化方法所证明的那样。
