66AbstractIn first project a new nickel nanocatalyst synthesized using reverse micelle technique andapplied in the Suzuki Miyaura reaction Initially bentonite the main component ismontmornolite was modified by sulfuric acid 4M Then by using reverse micelletechnique nanoparticles of nickel was prepared and they were immobilized on modifiedbentonite Different tecniques such as FTIR BET SEM ICP and XRD were used forcharacterization of the catalyst The synthesized catalyst was tested for suzuki reaction at120 C and 8 h with 100 selectivity The products were analysed by GCchromatography In second project a new palladium nanocatalyst synthesized using reversmicelle technique and applied in the Suzuki Miyaura reaction too Initially SBA 15synthesized Then by using reverse micelle technique nanoparticles of palladium wasprepared 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 synthesizedcatalyst was tested for suzuki reaction at 70 C and 2 h with 100 selectivity Theproducts were analysed by GC chromatography In the suzuki reaction phenylboronic acidwas 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 theend 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 catalystsused traditionally for the Suzuki reaction
