METHOD OF PRODUCING BETA-DIKETONATE OF PALLADIUM (II) Russian patent published in 2018 - IPC C07F15/00 C07C49/92 

FIELD: chemistry.

SUBSTANCE: method involves reacting beta-diketone with a solution of a palladium salt in an organic solvent, followed by the separation of the desired product from the solution. As the initial reactant, metallic palladium is used in the form of a powder, to the calculated amount of which nitric acid is added and mixed until the complete dissolution of palladium. Then the resulting palladium nitrate solution (II) is diluted with water to pH 2.0-3.0, and the solution of the corresponding beta-diketonea (HL) is added, dissolved in chloroform, followed by stirring the reaction mixture at room temperature for 20-30 minutes, separating the organic phase, and allocating the target product from the solution of chloroform by stripping the latter. As the beta-diketone, a compound of the general formula R'C(O)CH₂C(O)R is used, where R' and R are alkyl or perfluoroalkyl.

EFFECT: simplification of the method and reduction of its duration while maintaining a high yield of the target product.
