Reduced Graphene Oxide as Recyclable Catalyst for Synthesis of Bis(aminothiocarbonyl)disulfides from Secondary Amines and Carbon Disulfide

摘要

The reaction of secondary amines with CS2 under mild conditions using reduced graphene oxide (rGO) as a green catalyst was reported, which provided an efficient access to the one-pot synthesis of bis(aminothiocar-bonyl)disulfides. The rGO can be recycled at least four times without any loss of catalytic activity. A plausible mechanism was proposed.
