General Description

Potassium acetylacetonate is a chemical compound with the molecular formula KC5H7O2. It is a metal acetylacetonate, which is a type of coordination compound containing a metal cation and the acetylacetonate anion. Potassium acetylacetonate is commonly used as a catalyst or reagent in organic synthesis, particularly in the preparation of various metal acetylacetonate complexes. It is also utilized as a stabilizer in the production of plastics and polymers, and as a chemical intermediate in the manufacturing of pharmaceuticals and other organic compounds. Additionally, this compound has been investigated for its potential application in dye-sensitized solar cells and as an additive in lubricants and fuels.

Labile Cu(I) catalyst/spectator Cu(II) species in copper-catalyzed C-C coupling reaction: Operando IR, in situ XANES/EXAFS evidence and kinetic investigations

Insights toward the Cu-catalyzed C-C coupling reaction were investigated through operando IR and in situ X-ray absorption near-edge structure/extended X-ray absorption fine structure. It was found that the Cu(I) complex formed from the reaction of CuI with β-diketone nucleophile was liable under the cross-coupling conditions, which is usually considered as active catalytic species. This labile Cu(I) complex could rapidly disproportionate to the spectator Cu(II) and Cu(0) species under the reaction conditions, which was an off-cycle process. In this copper-catalyzed C-C coupling reaction, β-diketone might act both as the substrate and the ligand.

Synthesis of ruthenium(iii) and rhodium(iii) tris-acetylacetonates and palladium(ii) bis-ketoiminate using microwave heating

Preparation of ruthenium(iii) and rhodium(iii) tris-acetylacetonates and palladium(ii) bisketoiminate (Pd(i-acac)2) under microwave irradiation using different synthetic conditions, both in the solid-phase and in solution, was studied with precise control of parameters. In the solid-phase systems, the preparation of the target product was hindered. The efficiency of the microwave heating increased when liquid phases of the reagent mixtures were used. For Pd(i-acac)2, the highest yield was achieved under elevated temperature of the process, with the reaction time decreasing to several minutes. A laboratory procedure for the microwave synthesis of ruthenium(iii) and rhodium(iii) tris-acetylacetonates and palladium(ii) bis-ketoiminate in aqueous solutions was developed, which allowed us to obtain them in 85, 55, and 80% yields, respectively. These yields are higher than those reported in the literature, with the process becoming considerably less time consuming and laborious.
