Synthesis and characterization of the Dimeric Ortho palladatedcomplex with 4 nitro benzyl methylene triphenylphosphorane and using for preparation of palladium supported on PVP for Suzuki and Heck cross coupling reaction Omolbanin Vahidnia o vahidnia@ch iut ac ir Department of chemistry Isfahan university of thechnology Isfahan 84156 83111 Degree M sc Language Farsi Supervisor Kazem Karami Karami@cc iut ac ir Abstract Palladium based catalysts particularly Nano scale palladium particles have recently drawnenormous attention In this thesis palladium nanoparticles supported on with poly N vinyl 2 pyrrolidone PVP were synthesized and used as heterogeneous catalyst in organic synthesis In order to do this and based on previous researches at first Pd I NO2 BPPY 2 complexwas synthesized by use of Palladium Chloride and 4 nitro benzyl methylenetriphenylphosphorane ligand After that Palladium Nano catalyst supported on Pd PVP 1 5 was made X ray diffraction scanning electron microscopy and transmission electronmicroscopy showed that the palladium particles were well distributed within the polymermatrix and were typically about 25 nm in diameter The catalyst was used for phenyl boronicacid with different aryl halides coupling Suzuki coupling reaction and styrene with differentaryl halides coupling Heck coupling reaction and the corresponding products showed highyield ranges After reactions the catalyst can be separated by simple method and used manytimes in repeating cycles without considerable loss in its activity Keywords Nano catalyst heterogeneous catalyst Suzuki coupling reaction Heckcoupling reaction
