Nafion–Fe: A New Efficient “Green” Lewis Acid Catalyst for the Ketonic Strecker Reaction
Catalysis Letters, 2013Co-Authors: G. K. Surya Prakash, Thomas Mathew, Inessa Bychinskaya, Eric R. Marinez, George A. OlahAbstract:The synthesis of various α-aminonitriles, precursors of α-amino Acids has been carried out in moderate to high yields and high purity by the Strecker reaction from ketones, aliphatic/aromatic amines and TMSCN using a new “green” Lewis Acid Catalyst, Nafion–Fe (iron Nafionate, Fe(III) salt of Nafion–H, a solid polymeric perfluoroalkanesulfonic Acid) under conventional thermal as well as microwave conditions. Microwave and solvent-free conditions applied in this method shorten the reaction times, improve the yields and diminishes the formation of side products. Strecker reaction occurs smoothly with secondary aliphatic amines also under these conditions which is not common under conventional conditions. Graphical Abstract

sulfonated graphene as water tolerant solid Acid Catalyst
Chemical Science, 2011Co-Authors: Junyi Ji, Guanghui Zhang, Hongyu Chen, Shulan Wang, Guoliang Zhang, Fengbao ZhangAbstract:Acid Catalysts are essential for various chemical reactions in the industrial hydrocarbon chemistry. Sulfonated carbon has shown promising application as a new, cheap and environmentally friendly solid Acid Catalyst. In this study, we prepared the sulfonated graphene Acid Catalyst, and it was characterized by electron microscopy, Raman spectroscopy, solid state 13C MAS NMR, energy dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). Catalytic hydrolysis of ethyl acetate shows that the sulfonated graphene has highly catalytic activity and can be repetitively used as a water-tolerant solid Acid Catalyst.
