FIELD: chemistry.SUBSTANCE: invention relates to a method of producing palladium (II) beta-diketonates or beta-ketoiminates. The method involves reacting a beta-diketone with a palladium salt solution in an organic solvent, followed by cooling the end product and separation thereof from the solution. The beta-diketone or beta-ketoimine used is the compound R'C(O)CHC(O)R or R'C(O)CHC(NH)R, respectively, where R', R denote alkyl or perfluoroalkyl or an alkoxy group, containing 1-4 carbon atoms, an aryl containing 4-10 carbon atoms, in different combinations. The palladium salt used is palladium (II) chloride. The reaction is carried out in a solvent selected from nitriles or amides of organic acids, in which starting components are dissolved, and which is infinitely miscible with water, in the presence of an equivalent amount of sodium or potassium hydroxide, or sodium or potassium carbonate. The end product is precipitated from the solution with water.EFFECT: invention enables to obtain an isomerically pure product with high output directly in a single-step synthesis process without using additional separation processes.3 cl, 5 dwg, 6 ex |
