Palladium(II) complexes with aminomethylphosphine ligands as catalysts for the heck reaction
Mustafa Kemal Yılmaz
New, aminomethyldiphosphine(P C N) ligands, ((C6 H5 ) 2 PCH2 ) 2 NR (R = C6 H3(CH3 )(OH) (1a), C6 H4 OC6 H5 (1b), C6 H4 SC6 H5 )(1c)) and their Pd(II) complexes have been syn-thesized and characterized. These complexes werefound to be efficient catalysts in the Heck reaction ofactivated and deactivated aryl halide with a varietyof olefins.
Synthesis and characterization of bis(diphenylphosphinomethyl)amino ligands and their Ni(II), Pd(II) complexes: Application to hydrogenation of styrene
Altan, Orhan
Transition metal complexes of Ni(II) and Pd(II) with ditertiary bis(diphenylphosphinomethyl)amino ligands, (Ph2PCH2)2NC(CH3)3 (1) and [(Ph2PCH2)Nm-PhSO3]Na (2) (Ph = phenyl), have been synthesized in good yields under nitrogen atmosphere by Schlenk technique. All complexes have been characterized using elemental analyses and spectroscopic techniques such as atomic absorption, FT-IR, and NMR (1H, 31P). Atomic absorption spectroscopic analysis showed that the reactions of ligands 1 and 2 with NiCl2 ⋅ 6H2O and [PdCl2(COD)] occurred in 1:1 molar ratio. The metal complexes [NiCl2(Ph2PCH2)2Nm-PhSO3Na] (4) and [PdCl2(Ph2PCH2)2Nm-PhSO3Na] (6) were found to be soluble in ethanolic and aqueous solutions, as well as slightly soluble in water. Electrochemical behaviors of complexes were investigated b...
