A dual-metal catalysis system including a newly prepared nanoparticle [SiO2@organic-linker(OL)@Pd(II)] and CuI was introduced with ultra-high catalytic activity (high turnover number (TON), up to 19 000) to a one-pot and odorless synthesis of unsymmetrical aryl sulfides by crossover C-S bond formation. The reaction proceeds via C-O bond activation of phenols and direct C-S bond formation in the presence of S8 as an oddorless sulfur source and aryl boronic acids under mild conditions (room temperature). The catalyst could be recycled up to five times without an obvious change in its activity.
一种双金属催化体系，包括一种新制备的纳米粒子[SiO2@有机连接体（OL）@Pd（II）]和 CuI，具有超高的催化活性（高周转数（TON），高达 19000），可用于一锅法、无臭合成不对称芳基硫醚，通过交叉 C-S 键形成。该反应在温和条件下（室温），以 S8 为无臭硫源和芳基硼酸，通过酚的 C-O 键活化和直接 C-S 键形成进行。催化剂可回收使用 5 次以上，活性无明显变化。
