  2-Phenylimidazole−PdCl₂ and 2-Phenylimidazoline−PdCl₂ Complexes: Single-Crystal and Powder X-ray Diffractometry, ¹H NMR Spectra, and Comparison of Catalytic Activities in Coupling Reactions

  摘要：

  Single-crystal X-ray diffractometry and powder X-ray diffractometry of the complexes dichlorobis(2phenyl-1H-imidazole)palladium(II) (1) and dichlorobis(2-phenyl-4,5-dihydro-1H-imidazole)palladium(II) (2) and H-1 NMR structure elucidation in DMF-d(7) solution are discussed. In the case of complex 1, we found that changing the solvent for recrystallization from a mixture of DMF and toluene (method A) to only DMF (method B) afforded complexes 2 and 2', having crystallographically different structures. H-1 NMR studies indicated that the spectra of the solid samples 2 and 2' are the same in DMF-d7. This indicated that the Pd-N bond rotates easily in solution, whereas complexes 2 and 2' coexist through strong packing in the solid state. The catalytic activities of Pd complexes 1 and 2 in coupling reactions such as the Mizoroki-Heck reaction and Suzuki-Miyaura coupling will also be disclosed.

  Several palladium complexes of the type [Pd(im)(2)Cl-2], [Pd(im)(3)Cl]Cl, and [Pd(im)(4)]Cl-2 (im = imidazole 1,1-methylimidazole 2, 1,2-dimethylimidazole 3, 1-butylimidazole 4, 4a, 1-phenylimidazole 6, 1-phenylimidazoline 7, and 1-methylimidazoline 8) were prepared and structurally characterized. The square planar structure of two new complexes with the composition [Pd(im)(4)]Cl-2 (2b, 4b) was confirmed by X-ray analysis. In solution, exchange of imidazole ligands leading to heteroleptic products was evidenced by ESI-MS studies. Two bis-ligated complexes, bearing 1-methylimidazole (2a) and 1-propoxymethylimidazole (5) ligands, were obtained in the reaction of palladium with imidazoles formed by deprotection of one nitrogen atom in the respective imidazolium halides. Catalytic Suzuki-Miyaura reactions were carried out using the obtained palladium complexes in isopropanol-water solution. High yields of the cross-coupling products were obtained at 40 and 60 degrees C when 2-bromotoluene, 4-bromotoluene, and 4-bromoanizole were used as substrates. (C) 2010 Elsevier B.V.
