研究发现,在 110°C 的 DMSO 中,使用 Na2CO3 为碱,TBATB 为试剂,纳米氧化铟是硫醇转化为硫化物的有效催化剂。此处,TBATB 通过铟表面原位生成溴中间体。可以用反应性较低的氯化物、硼酸和硫醇以优异的产率合成各种芳基硫醚。
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.
