91 Preparation and characterization of heterogeneous and renewable nanocatalysts using the immobilized copper complex and evaluation of their performance as catalysts in the coupling reactions Seyed Mostafa Hosseini Mohosseini967@gmail com 2015Department of Chemistry Isfahan University of Technology 84156 83111 Isfahan IranProf A R Hajipour Email haji@cc iut ac ir Isfahan University of Technology 84156 83111 Isfahan IranABSTRACTHerein application of copper nanoparticles supported on silica surfaces as efficient catalysts were studied in carbon carbon carbon nitrogen and carbon sulfur bond formation under conventional heating conditions in an oil bath First copper I nanoparticles activity supported on the silica surface of in the Sonogashira cross coupling reactionwere studied The yields under optimized conditions of using KOH as base DMF as solvent at 135 C temperatureunder N2 gas were good In the next section the activity of copper nanoparticles supported on the surface of silica inthe amination reaction was studied The obtained product under optimized conditions of using K2CO3 as base DMF H2O 1 1 as solvent at 100 C temperature under N2 gas were good Results showed that copper supported onthe surface of silica has high efficiency in the two cross coupling reaction Finally the activity of copper nanoparticles supported on the surface of MCM 41 was studied in the synthesis ofbenzyl phenyl sulfides The used catalyst in this reaction has good activity The obtained yields under optimizedconditions of using K2CO3 as base H2O EtOH 1 1 as solvent at 100 C temperature were good Keywords Copper nanoparticles supported on the surfaces of silica Catalyst Amination reaction Carbon Sulfur couplingreaction sonogashira reaction
