title: Nano indium oxide as a recyclable catalyst for C-S cross-coupling of thiols with aryl halides under ligand free conditions.
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.
