An application for dechalcogenization of aryl dichalcogenides via copper catalysis to synthesize aryl chalcogenides is disclosed. This approach is highlighted by the practical conditions, broad substrate scope, and good functional group tolerance with several sensitive groups such as aldehyde, ketone, ester, amide, cyanide, alkene, nitro, and methylsulfonyl. Furthermore, the robustness of this methodology
公开了一种通过铜催化将芳族二硫属元素进行脱硫反应以合成芳基硫属元素化物的应用。实际条件,广泛的底物范围以及对几个敏感基团(如醛,酮,酯,酰胺,氰化物,烯烃,硝基和甲基磺酰基)的良好官能团耐受性突出了该方法。此外,该方法的鲁棒性通过雌酮的后期修饰和伏替西汀的合成来描述。值得注意的是,通过该方案成功地完成了在较温和条件下具有较大环张力的更具挑战性的有机材料的合成,以及某些不能通过金属催化的芳基卤素偶合反应合成的含卤素的二芳基硫醚的合成。
