  Monomer and dimer complexes of copper(II) acetate with pyridine and picolines—II. Solution equilibria by spectrophotometric and NMR magnetic measurements

  摘要：

  Equilibrium constants (K) for the reaction: [Cu(OAc)2.L]2+2L reversible 2[Cu(OAc)2.L2], where OAc is the acetate anion and L = pyridine (py), beta-picoline (beta-pic) or gamma-picoline (gamma-pic), were determined from spectrophotometric and variable-temperature magnetic measurements in chloroform solutions. Good agreement was found between the two methods. The small K values (0.01-0.45) found for the equilibria are consistent with the observed instability of the monomers in chloroform, and increase in the order: py < beta-pic < gamma-pic. The position of the beta-picoline system, for which no crystalline monomer could be isolated, and the anomalous behaviour of alpha-picoline within this series are discussed in terms of crystal-packing requirements arising from the steric properties of these ligands. Thermodynamic parameters for the equilibria were obtained from the temperature dependence of K. The values of DELTA-H(Kelvin) and DELTA-S(Kelvin) are in close agreement with those found for adduct formation of related copper(II) chelates with these ligands, and are discussed in terms of contributions from electronics and structural reorganization, bond formation and solvation effects.

  Dicopper(II) tetracarboxylate complexes of the type [Cu2(µ-O2CR)4L2] have received a great deal of attention from inorganic chemists in the past. However, these well-known species have been rarely studied as catalysts. Herein we describe the synthesis, UV–Vis spectral behavior and catalytic properties of six species of this type, viz. [Cu2(µ-O2CC6H5)4(py)2] (I), [Cu2(µ-O2CC6H5)4(4-CNpy)2] (II), [Cu2

  摘要过去，[Cu2（µ-O2CR）4L2]型四羧酸双铜（II）配合物受到了无机化学家的广泛关注。但是，很少研究这些众所周知的物质作为催化剂。在这里，我们描述了这种六种物质的合成，UV-Vis光谱行为和催化特性。[Cu2（µ-O2CC6H5）4（py）2]（I），[Cu2（µ-O2CC6H5）4（4-CNpy）2]（II），[Cu2（µ-O2CC6H5）4（3-CNpy）2 ]（III），[Cu2（µ-O2CCH3）4（py）2]（IV），[Cu2（µ-O2CC7H15）4（4-CNpy）2]（V）和[Cu2（µ-O2CC7H15）4（ 3-CNpy）2]（VI）。正如其固态和溶液的UV-Vis光谱所证明的那样，这些络合物在溶液中保留了其双核完整性，因此已被研究为苯乙烯环氧化的均相催化剂。它们在叔丁基过氧化氢水溶液（TBHP）作为末端氧化剂的情况下，对苯乙烯的氧化表现出非常好的催化活性。反应

  Copper(II) acetate reacts with formaldehyde oxime (1 : 1) in a nitrite solvent, RCN at ca. 350 K to give a pale blue-green complex [Cu3(O2CMe)5(RCONH2)(CH2NOH)2](R = Me or Ph). The complex having R = Me reacts with acetic anhydride in acetonitrile to give CuCN, [Cu2(O2CMe)4(OH2)2], and [Cu2(CN)2(NCMe)], and with pyridine (py) to give [Cu(O2CMe)(CH2NOH)2], [Cu2(O2CMe)4(py)2], and acetamide.

  Cu(O2CMe)2–pyridine derivative (L) complexes [L = pyridine (py), 2-methylpyridine (2Me-py), 3,4-dimethylpyridine (3,4Me2-py), and isoquinoline (i-quin)] have been studied by u.v. and e.s.r. spectroscopic methods. The results are interpreted in terms of the equilibrium 2[Cu(O2CMe)2L2]⇌[Cu2(O2CMe)4L2]+ 2L. The relative stability of the binuclear complexes in solution strongly depends on the basicity
