Nano sized indium oxide is found to be an efficient catalyst for the conversion of thiols to sulfides using Na2CO3 as base and TBATB as reagent in DMSO at 110 °C. Here in situ generation of bromo intermediate by TBATB takes place through indium surface. A variety of aryl sulfides can be synthesized in excellent yields from less reactive chlorides, boronic acids and thiols.
已发现纳米级氧化铟是一种高效催化剂，可在110°C的二甲基亚砜（DMSO）中，以碳酸钠作为碱、四丁基三溴化铵（TBATB）作为试剂，将硫醇转化为硫化物。在此过程中，TBATB通过铟表面原位生成溴代中间体。多种芳基硫化物可由活性较低的氯化物、硼酸和硫醇以优异的产率合成。
