Crystal structure and thermochemical properties of potassium pyruvate C3H3O3K(s)

One important compound potassium pyruvate C3H3O3K(s) is synthesized and characterized by chemical analysis, elemental analysis, and X-ray crystallography. X-ray single-crystal structural analysis reveals that the compound is formed by one CH3COCOO? anion and one metal cation K+. An obvious feature of the crystal structure of the compound is the formation of the five-membered chelate ring, and it is good for the stability of the compound in structure. The lattice potential energy of the compound and ionic volume of the anion CH3COCOO? are obtained from crystallographic data. The lattice potential energy is determined to be: UPOT[C3H3O3K(s)]?=?567.7?kJ?mol?1. The V? (the volume of the anion CH3COCOO?) is estimated to be 0.088?nm3. Molar enthalpies of dissolution of the compound at various molalities in the double-distilled water are measured by use of an isoperibol solution-reaction calorimeter at 298.15?K. According to Pitzer’s electrolyte solution theory, molar enthalpy of dissolution of C3H3O3K(s) at infinite dilution is derived to be 22.9?kJ?mol?1. The values of relative apparent molar enthalpies (ΦL), relative partial molar enthalpies (Lˉ 2) of the compound, and relative partial molar enthalpies (Lˉ 1) of the solvent (water) at different concentrations m/(mol?kg?1) are derived from the experimental values of the enthalpies of dissolution of the compound. Finally, the molar enthalpy of hydration of the anion CH3COCOO?(g) is calculated to be ?227.8?kJ?mol?1 by the design of the thermochemical cycle.

Synthesis of 6-acyl phenanthridines by oxidative radical decarboxylation-cyclization of α-oxocarboxylates and isocyanides

A silver catalysed synthesis of 6-acyl phenanthridines by oxidative radical decarboxylation-cyclization of α-oxocarboxylates and isocyanides was developed. This reaction provided a novel method to realize C1 insertion via a radical process and various functional groups were well-tolerated. The Royal Society of Chemistry.

Method for producing alkali metal and alkaline earth metal pyruvates

A method for producing alkali metal and alkaline earth metal pyruvates is disclosed, in which salts of organic acids or acidic organic keto or hydroxy compounds containing as cation one from the group comprising Li, Na, K, Rb, Cs, Mg, Sr and Ba, or mixtures of these salts, are reacted with pyruvic acid at a temperature ranging from ?20 to +120°C., if necessary in the presence of a solvent or diluent. In this way, alkali metal and alkaline earth metal pyruvates of high purity are obtained, which can be largely anhydrous and have a very long shelf life. In addition, novel Rb, Cs, Sr and Ba pyruvates are disclosed. These pyruvates are used, for example, to enhance endurance and strength in the field of sport, as protective substances for body cells and tissues, and as food supplements. They are also used for technical applications.
