Synthesis and characterization of stabilized phosphorous ylide FBPPY complex with silver and orthopalladated complexes of phosphorus ylide PhBPPY with some aminoacids N O Masoud Edalati m edalati@ch iut ac ir Date of Submission 1 20 2014 Department of Chemistry Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Kazem Karami Karmi@cc iut ac ir Abstract In this thesis phosphorus ylides 4 phenyl benzoyl methylene triphenylphosphorane PhBPPY and 4 fluorobenzoyl methylene triphenylphosphorane FBPPY were synthesized through two steps involving the formation and depororotonation of phosphonium salt Mononuclear complex Ag FBPPY 2 OTf and orthopalladated dinuclear complex Pd OAc PhBPPY 2 have been obtained respectively through the reaction of FBPPY with silver I trifluoro methane sulfanate and PhBPPY with Pd OAc 2 The dinuclear complex was reacted with aminoacids phenylalanine valine leucine iso leucine and alanine to obtain mononuclear complexes of general formula Pd aminoacid PhBPPY Synthesized complexes were identified and fully characterized by elemental analysis and spectroscopic studies FT IR and 1H 31P 1H 13C 1H NMR Crystal structure of Ag FBPPY 2 OTf was confirmed through the X ray analysis The CO band appears at higher frequencies compared to that found in free ylide indicative of C coordination of ylide PC is appeared at the lower frequencies due to the charge density reduction 1H NMR of all complexes show signals for ylidic hydrogen in downfield chemical shifts in comparison with the free ylide confirming the C coordination of ylide which reduces the charge density on the aromatic ring Existence of two chiral center in each structure leads to the creation of four sets of peak for each hydrogen 31P 1H NMR spectra of all complexes confirm four isomers for each complex Computational studies were done by Gussion 09 DFT method using LANL2MB basis set It is consist of mulliken atomic charges dipolmoments HOMO LUMO energies and optimized structures of complexes Considering the chairalaty of ylidic carbon DFT calculation showed that the structure A in which carboxylate group is trans to the ylidic carbon is more stable than B Keywords Phosphorus ylides silver I trifluoro methane sulfanate Orthopalladation Amino acids PDF created with pdfFactory trial version www pdffactory com
