In first project a new nickel nanocatalyst synthesized using reverse micelle technique, and applied in the Suzuki Miyaura reaction. Initially, bentonite (the main component is montmornolite) was modified by sulfuric acid (4M). Then, by using reverse micelle technique nanoparticles of nickel was prepared, and they were immobilized on modified bentonite. Different tecniques such as FTIR, BET, SEM, ICP and XRD were used for characterization of the catalyst. The synthesized catalyst was tested for suzuki reaction at 120 °C and 8 h with 100% selectivity. The products were analysed by GC chromatography. In second project a new palladium nanocatalyst synthesized using revers micelle technique , and applied in the Suzuki Miyaura reaction, too. Initially, SBA-15 synthesized.Then, by using reverse micelle technique nanoparticles of palladium was prepared, and they were immobilized on SBA-15. Different tecniques such as FT-IR, BET, SEM, ICP and XRD were used for characterization of the catalyst. The synthesized catalyst was tested for suzuki reaction at 70 °C and 2 h with 100% selectivity. The products were analysed by GC chromatography. In the suzuki reaction phenylboronic acid was reacted with various arylhalides such as Iodobenzene, 4-iodo nitrobenzene, 3-Bromo-Nitro benzene. Ethanol was used as the best solvent and K2CO3 used as the base. At the end of reaction, the catalysts were recovered and have been reused several times . Hence ,this reaction is beneficial for using relatively cheap, easily and fast prepared reagents. These heterogeneous catalysts could be introduced as a substitute for expensive catalysts used traditionally for the Suzuki reaction.
