Synthesis, characterization and catalytic activity of novel N-heterocyclic carbene-palladium complexes

WOS: 000269288700027PubMed ID: 20449152The reaction of Pd(OAc)(2) with 1-(benzhydryl)-3-(alkyl) benzimidazolium salts 1a-d yields trans-bis[1-(benzhydryl)-3-(alkyl)benzimidazolin-2-ylidene]dibromopalladium(II) complexes (2a-d) which were characterized by elemental analysis, NMR spectroscopy and the molecular structures of 2b, and 2d were determined by X-ray crystallography. The catalytic activity of PdBr(2)bis(benzimidazolin-2- ylidene) complexes 2a-d was evaluated in the direct arylation reaction of benzothiazole with bromobenzene derivatives.Technological and Scientific Research Council of Turkey TUBITAK-CNRS (France)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [TBAG-U/181 (106T716)]; Inonu University Research FundInonu University [2009/13]; Faculty of Arts and Sciences, Ondokuz Mayis University, TurkeyOndokuz Mayis University [F279]This work was financially supported by the Technological and Scientific Research Council of Turkey TUBITAK-CNRS (France) [TBAG-U/181 (106T716)], Inonu University Research Fund (I.U.B.A.P: 2009/13) and the Faculty of Arts and Sciences, Ondokuz Mayis University, Turkey, for the use of the Stoe IPDS-II diffractometer (purchased from grant no.
