Synthesis, characterization, luminescence and catalytic properties of copper(I) complexes with N-(2-pyridylmethylene)-1,5-dimethyl-2-pyrazole-3-(2H)-one and triphenylphosphine as ligands

A series of copper(I) complexes of the formula [Cu(L)(PPh3)2]X (1–4) [where L = N-(2-pyridylmethylene)-1,5-dimethyl-2-pyrazole-3-(2H)-one; PPh3= triphenylphosphine, X = Cl(1), ClO4(2), BF4(3) and PF6(4)] have been prepared by the condensation of 4-aminoantipyrine with pyridine-2-carboxaldehyde followed by reaction with CuCl, [Cu(MeCN)4]ClO4, [Cu(MeCN)4]BF4,[Cu(MeCN)4]PF6in presence of triphenylphosphine as a coligand. A single crystal X-ray diffraction study of the representative complex [Cu(L)(PPh3)2]BF4(3) reveals a distorted tetrahedral geometry around Cu(I). Complexes 1–4 exhibit quasireversible redox behavior corresponding to a Cu(I)/Cu(II) couple. All complexes show orange-red emission as a result of fluorescence from an intra-ligand charge transition (ILCT) with some metal to ligand charge transfer (MLCT) character. Significant increase in size of the counter anion shows marked effect on quantum efficiency and lifetime of the complexes. The catalytic efficiency of the complexes was tested and it was found that all the complexes worked as an effective catalyst in the Sonogashira coupling of phenylacetylene with aryl halides in good yield.

Copper(I) complexes of 2-methoxy-(5-trifluoromethyl-phenyl)-pyridine-2yl-methylene-amine: Impact of phosphine ancillary ligands on luminescence and catalytic properties of the copper(I) complexes

Some copper(I) complexes of the type [Cu(L)(PPh3)2]X (X = Cl (1a), CN (1b), ClO4 (1c), BF4 (1d)) and [Cu(L)(dppe)]X (X = Cl (2a), CN (2b), ClO4 (2c) and BF4 (2d)) [where L = 2-methoxy-(5-trifluoromethyl-phenyl)-pyridine-2yl-methylene-amine; PPh3 = triphenylphosphine; dppe = 1,2-bis(diphenylphosphino)ethane] have been prepared and characterized on the basis of elemental analyses, IR, UV-Vis, 1H NMR and 31P NMR spectral studies. The representative complex of the series 1d and 2c are characterized by single crystal X-ray diffraction which reveal that, in each complex the central copper(I) ion assumes the irregular pseudo-tetrahedral geometry. All the complexes display a weak MLCT that varies considerably with phosphine ligands. Quasireversible redox behavior is accounted for all complexes corresponding to Cu(I)/Cu(II) couple and is sensitive to phosphine ligands. All the complexes exhibit blue-green emission originate from intra-ligand charge transfer (ILCT), ligand to ligand charge transfer (LLCT) transitions or mixture of them and vary markedly with the phosphine ligands. The copper(I) complexes with dppe ancillary ligand shows greater activity for the amination of iodobenzene as compared to PPh3 ancillary ligand in the complexes.
