95 Application of Bis 1 Benzyl 4 Aza 1 Azoniabicyclo 2 2 2 Octane Tetra Chloro Dichloro Dipalladyt II Catalyst in The Synthesis and Characterization of Stille Hiyama Homo Coupling and Sonogashira Products Narges Najafi mohsenabad n najafimohsenabad@ch iut ac ir December 18 2012 Department of Chemistry Isfahan University of Technology 84156 83111 Isfahan Iran Degree M Sc Language Farsi Prof A R Hajipour Email haji@cc iut ac ir Abstract Herein an efficient and effective palladium salt was synthesized using the salt of 1 benzyl 4 aza 1 azoniabicyclo 2 2 2 octane chloride n benzyl DABCO chloride and palladium chloride was investigated in the Stille reaction under conventional heating and microwave irradiation conditions The complex was active and efficient catalyst for the Stille reaction of aryl halides The yields were excellent using a catalytic amount of complex 1 in DMF at 120 C In the next section Hiyama cross coupling reaction of various aryl halides with triethoxy phenyl silane under conventional heating and microwave irradiation conditions were created the corresponding products in excellent yields in NMP as solvent and CsF as base at 120 C The symmetrical biaryls were obtained via homo coupling reaction of various aryl halides in NMP as the solvent and K2CO3 as base at 120 C In comparison to conventional heating conditions the reactions under microwave irradiation gave higher yields in shorter reaction time The catalyst has great activity in Sonogashira reaction and The yields were good to excellent under optimized conditions using piperidine as base water as solvent at 60 C temperature Keywords catalytic palladium Stille reaction Hiyama reaction homo coupling reaction Sonogashira reaction microwave irradiation PDF created with pdfFactory trial version www pdffactory com
