Abstract
An efficient ligand-free C-S cross-coupling of aryl halides with aromatic/alkyl thiols has been developed using a catalytic amount of nanocrystalline indium oxide as a recyclable catalyst with KOH as the base in DMSO at 135 degrees C. A variety of aryl sulfides can be synthesized in excellent yields utilizing this protocol.
摘要
已开发出一种高效的无配体芳基卤化物与芳族/烷基硫醇的C-S交叉偶联反应，使用催化量的纳米晶氧化铟作为可循环使用的催化剂，以氢氧化钾为碱，在二甲基亚砜中于135℃下进行反应。利用该方法可以以优异的产率合成多种芳基硫化物。
