Economical and recyclable graphene oxide-based nanocomposites catalyzed Ullmann reaction of aryl chloride in hmim Tf2N/supercritical carbon dioxide system
Palladium nanoparticles (Pd NPs)/graphene oxide (GO) nanocomposites catalyzed Ullmann reaction of aryl chloride in hmimTf2N/supercritical carbon dioxide (ScCO2) system were developed. The hmimTf2N/ ScCO2 system showed superior competitiveness in product separation, catalyst recycling as well as environmental consideration. Further investigations showed that GO could replace the traditional active hydrogen donor readily with improved product separation efficiency. The use of hmimTf2N led to obvious improved stability of the catalyst. Carbon dioxide was found to significantly promote the selectivity of the graphene oxide-based nanocomposites catalyzed Ullmann reaction of aryl chloride.
