Synthesis, Structural Characterization, and Catalytic Evaluation of Phosphinoferrocene Ligands Bearing Extended Urea-Amide Substituents

Popis výsledku v původním jazyce

New phosphinoferrocene ligands bearing extended polar amidourea pendants with the general formula Ph2PfcCONHCH2CH2NHCONR2 (1; R2 = H2 (b), H/Et (c), Me2 (d), H/Ph (e)) and their model bis-amide Ph2PfcCONHCH2CH2NHCOCH3 (1a) were prepared in good yields byamidation of 1'-(diphenylphosphino)ferrocene-l-carboxylic acid (Hdpf) with the appropriate amines in the presence of peptide coupling reagents. These ferrocene-based phosphinoureas were further employed as ligands in palladium(II) complexes with h3-allyl and NC-chelating supporting ligands: viz., [PdCl(h3-C3H5)(1-kP)] (5a-e) and [PdCl(L-NC)(1-kP)] (6a-e; L-NC = [2-(dimethyl-amino-kN)methyl]phenyl-kC-1). Both the free ligands and their Pd(II) complexes were characterized by spectroscopic methods (multinuclear NMR, IR, and MS) and by elemental analysis. The molecular structures of 1b.CH3OH, 1c, 5b,c, 6a, and two additional model complexes, [PdCl(h3-C3H5)(Hdpf-kP))] and [PdCl(h3-C3H5)(Ph2PfcCONH2-kappa P)], were determined by single-cryst
