  Synthesis and properties of lanthanide complexes with tetrapyrazinoporphyrazine and its substituted derivatives

  摘要：

  Reactions of dicyanopyrazine and its tert-butyl-, diphenyl-, and dipyridyl-substituted derivatives with erbium, thulium, ytterbium, and lutetium chlorides, acetates, and acetylacetonates gave the corresponding tetrapyrazinoporphyrazine metal complexes which were characterized by elemental analyses, and IR, H-1 NMR, and electronic absorption spectra. The stability of the complexes to thermooxidative decomposition in air was also studied.

  lanthanoid Ln(III) complexes was investigated in Me2SO including n-Bu4N(acac) and n-Bu4N(dibm) as ligands (where acac is the acetylacetonate anion and dibm is the diisobutrylmethanate anion). Reversible one electron reduction waves corresponding to Ln(III) complexes→Ln(II) complexes were observed in the concentration range of 5–20 mM of the ligands, including 1 mM lanthanoid perchlorates and 0.1 M TEAP

  New symmetrical metal complexes of the rare-earth element phthalocyanines were synthesized by the reaction of 4,5-bis(cyclohexylmethoxy)phthalonitrile, obtained for the first time, with the rare-earth element salts, as well as starting from the corresponding free phthalocyanine. A correlation between method of the synthesis and the reaction product compositions was studied. Structures of the complexes obtained were confirmed by mass spectrometry, X-ray crystallography, and electronic absorption spectroscopy. All the metal complexes are well soluble in organic solvents.
