Synthesis method for copper octoate

The embodiment of the invention provides a synthesis method for copper octoate, and relates to the field of organic synthesis. The synthesis method for copper octoate comprises the following steps that n-caprylic acid and copper oxide are mixed with a solvent with the mole ratio being 0.1-2:1, n-caprylic acid is dissolved into a solvent, a reaction is performed under the condition that the temperature is higher than the boiling point of the solvent, and a reactant is obtained; the reactant is subjected to solid-liquid separation. The copper octoate product is obtained by adopting the synthesismethod for copper octoate, and the purity of copper octoate in the copper octoate product reaches 99% or above. The synthesis method for copper octoate is simple, and the copper octoate product is high in purity.

Copper(II) carboxylates with 4-aminopyridine: Neutral mononuclear structures, isomerism of aceto compounds and a novel tetranuclear structure

Reactions of copper(II) carboxylates with 4-aminopyridine (4-apy) were investigated and their products structurally characterized by single crystal X-ray diffraction. Reaction of copper(II) acetate resulted in two isomers of a monomeric complex of composition Cu(ac)2(4-apy)2 with markedly different stabilities: the violet form, 1, unstable in air and the blue, stable form, 2. In both isomers the ligands are arranged around the copper atom in a trans geometry. The 4-apy ligands lie almost in the plane in 1, while they are twisted with respect to each other in 2. Variations were observed also in the coordination of the acetate groups to the copper ion. The energy difference between the two isomers was obtained on the basis of ab initio MO calculations. The result agrees well with the observed relative stabilities in the solid state. Monomeric complexes of the same stoichiometry were obtained also by the reaction of Cu(II) hexanoate and heptanoate with 4-apy. The violet Cu(hex)2(4-apy)2, 3, and Cu(hep)2(4-apy)2, 4, are isostructural and possess trans geometry of the ligands around the copper centre. Reaction of 4-apy with Cu(II) octanoate lead to formation of a novel, unprecedented basic centrosymmetric tetranuclear compound of composition Cu4(oct)6(OH)2(4-apy)2, 5. Complex 5 contains bidentate bridging and monoatomic bridging carboxylate groups, triply bridging hydroxyl groups and 4-aminopyridine as a terminal ligand. In all five compounds 4-apy is coordinated through the endocyclic nitrogen atom only.

THE DIRECT ELECTROCHEMICAL SYNTHESIS OF SOME TRANSITION METAL CARBOXYLATES

The transition metal carboxylates M(O2CR)n (M=Cr, R=C2H5, C6H5, n=3; M=Mn, Fe, Ni, R=CH3, C2H5, C6H5, n-C7H15, n=2, not all combinations) have been prepared by oxidising suitable metal anodes electrochemically in solutions of RCOOH in acetonitrile.With Co and Cu, a wide range of carboxylic acids (R=C2H5, c-C3H5, c-C5H9, C6H5, n-C4H9, n-C7H15, 2-ethylhexanoic, oleic, linoleic) has been used succesfully to give M(O2CR)2.The advantages of the method are discussed.The preparation of Cu(O2CR)2 involves the prior formation of CuO2CR at the anode, followed by oxidation by the solvent.
