Doraswamy, Uma published the artcileStudies in some β-keto ester complexes, Quality Control of 14284-06-1, the publication is Journal of the Indian Chemical Society (1976), 53(1), 100-2, database is CAplus.

Proton-ligand and metal (Cu2+, Ni2+, Zn2+, Be2+) complex stability constants were determined for the β-keto esters Et-, Et-2-Me-, Et-2-Et-, Et-2-Pr-, Et-2-iso-Pr-, and Et-2-Bu-acetoacetate by pH titration in 50 volume % aqueous dioxane at 30° and ionic strength 0.2. The inductive and steric effects of the alkyl substituents result in a decreased stability of the metal complexes compared to the β-diketone complexes.

An economic, mild and efficient copper-catalyzed methodol. for the N-arylation of heterocycles was optimized using potassium aryltrifluoroborates in water. E.g., a pre-formed copper(II) Et acetoacetate complex catalyzed the N-arylation of imidazole by PhBF₃K to give 26% 1-phenylimidazole.

Corain, B. published the artcileCarbon-carbon bond formation upon addition of cyanogen to metal-coordinated β-carbonylenolato and β-ketoiminato ligands, Quality Control of 14284-06-1, the publication is Journal of Organometallic Chemistry (1982), 232(2), C59-C61, database is CAplus.

The addition of C₂N₂ to a variety of metal-coordinated β-carbonylenolato and β-ketoiminato ligands under ambient conditions affords novel compounds bearing cyanoimino-substituted organometallic rings. The key step of this process is the ready formation of a C-C σ bond upon insertion of C₂N₂ into the C-H methino bond.

Corain, B. published the artcileReactivity of cyanogen toward compounds containing active hydrogens at carbon. 5. Cyanoimination reaction of β-keto enolato and Schiff-base complexes of copper and nickel, Application of Copper(II) ethylacetoacetate, the publication is Inorganic Chemistry (1983), 22(19), 2744-9, database is CAplus.

Bis(β-keto enolato)copper(II) complexes and Ni(II) and Cu(II) complexes of the Schiff-base condensation products of 1,3-diketones and diamines react with cyanogen in chlorinated solvents to give cyanoimino-substituted organometallic rings. The reactions occur with high yields and display rates that are strongly affected by the central metal and by the nature of the substituents on the ligands. The new compounds were fully characterized by elemental anal., m.ps., IR and electronic spectroscopy, mass spectra, and thermal anal. I was characterized by x-ray single-crystal anal. The space group is P2₁/n, Z = 4, with a 19.863(9), b 12.184(8), c 9.739(6) Å, and β 98.4(1)°.

Perez, Yolanda published the artcileCopper-containing catalysts for solvent-free selective oxidation of benzyl alcohol, Computed Properties of 14284-06-1, the publication is Journal of Molecular Catalysis A: Chemical (2012), 45-56, database is CAplus.

Two different methods for the preparation of copper-containing catalysts have been described. Copper (II) ethylacetoacetate or copper (II) nitrate metallic precursors have been immobilized onto previously organofunctionalized MCM-41 material with N ⁴-(3-(triethoxysilyl)propyl)pyrimidine-2,4,6-triamine (DAPyPTS) compound The amino hybrid materials have been prepared by using both post-synthesis and co-condensation methods. In addition, the immobilization has been performed using organic and aqueous media. The catalysts have been characterized using X-ray diffraction (XRD), N₂ adsorption-desorption, inductively coupled plasma-at. emission spectroscopy (ICP-AES), scanning electron microscope (SEM) with energy-dispersive X-ray (EDX), elemental anal., ¹H, ¹³C and ²⁸Si MAS NMR, FT-IR and DRUV-vis spectroscopy. Copper-containing catalysts have been tested in the benzyl alc. oxidation with TBHP and H₂O₂ as oxidants and under solventless conditions. High selective (97%) to benzaldehyde was achieved using TBHP as oxidant and the copper (II) ethylacetoacetate immobilized onto organofunctionalized MCM-41 as catalyst under solventless conditions.

Palaniandavar, M. published the artcileSpectral and electrochemical behavior of some copper(II) complexes with CuO₄ chromophore, Synthetic Route of 14284-06-1, the publication is Indian Journal of Chemistry, Section A: Inorganic, Bio-inorganic, Physical, Theoretical & Analytical Chemistry (1995), 34A(10), 803-8, database is CAplus.

A few mixed ligand complexes [Cu(TCA)(L)] [where TCA = trichloroacetate; HL = 2,2,6,6-tetramethyl-3,5-heptanedione (DPM), 2,6-dimethyl-3,5-heptanedione (DMHD) and o-hydroxybenzophenone (OHBP)] were prepared and characterized by IR, electronic and EPR spectra and compared with those of the corresponding CuL₂ and other [Cu(TCA)(L)] chelates [where HL = acetylacetone (ACAC), ethylacetoacetate (EAA), salicylaldehyde (SAL) and o-hydroxyacetophenone (OHAP)] to illustrate the nature of bonding of TCA with Cu(II). The Cu^II/Cu^I redox potentials of the bis-chelates vary in the order, DPM < MDHD < ACAC < EAA; SAL ≈ OHAP < OHBP; they shift towards more neg. values as the number of electron repelling Me groups increases. For mixed ligand complexes, the potentials are more pos. than those of their resp. bis-complexes and vary in the order, DPM > DMHD > ACAC > EAA; SAL < OHAP < OHBP. All the above results suggest that the replacement in L in CuL₂ by TCA decreases the delocalization of electron d., more in o-hydroxyarylcarbonyl rather than in β-diketonate complexes.
