Role of TBATB in nano indium oxide catalyzed C-S bond formation

Abstract

Nano sized indium oxide is found to be an efficient catalyst for the conversion of thiols to sulfides using Na 2 CO 3 as base and TBATB as reagent in DMSO at 110â €‰°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.
