used groups in organic synthesis. Here, a a series of thianthrenium salts have been synthesized that act as reliable alkylation reagents and readily engage in copper-catalyzed Sonogashira reactions to build C(sp3)−C(sp) bonds under mild photochemical conditions. Diverse alkyl thianthrenium salts, including methyl and disubstituted thianthrenium salts, are employed with great functional breadth, since
烷基是有机合成中应用最广泛的基团之一。在这里,已经合成了一系列的铪盐,它们作为可靠的烷基化试剂,可以很容易地参与铜催化的 Sonogashira 反应,在温和的光化学条件下建立 C(sp 3 )-C(sp) 键。由于敏感的 Cl、Br 和 I 原子在常规方法中耐受性差,因此可以使用多种烷基铪盐,包括甲基和双取代的铪盐,具有很大的功能广度。在铜催化的熊田反应中也证明了所开发的烷基试剂的通用性。
