A wide variety of diaryl sulfides has been synthesized in excellent yields via C–S cross-couplings of aryl/heteroaryl halides with aromatic/heteroaromatic thiols in the presence of palladium nanoparticles immobilized on nanosilica triazine dendritic polymer (Pd np -nSTDP) as a reusable catalyst under thermal conditions and microwave irradiation. Pd np -nSTDP also showed excellent catalytic activity
在固定在纳米二氧化硅三嗪树枝状聚合物 (Pd np -nSTDP) 上的钯纳米粒子存在下,通过芳基/杂芳基卤化物与芳族/杂芳族硫醇的 C-S 交叉偶联,以优异的产率合成了多种二芳基硫化物。在热条件和微波辐射下的催化剂。Pd np -nSTDP 还表现出优异的催化活性,可通过一锅多 C-S 交叉制备一系列以苯、吡啶、嘧啶和/或 1,3,5-三嗪为中心核的二硫化物和三硫化物。 -偶联反应。
