FIELD: chemistry.SUBSTANCE: invention can be used in chemical industry. The method of producing disubstituted dinitrite compounds of palladium includes reacting palladium nitrate solution with NO and evaporating the obtained solution. The palladium nitrate solution is evaporated to palladium content of not less than 100 g/l and free nitric acid of not more than 300 g/l. NO is then released into said solution at 15-40°C until the end of precipitation of a nitrite-nitrosyl compound of palladium in the presence of perchloric acid in amount of 0.5-10% of the molar amount of palladium in the solution. Further, the formed nitrite-nitrosyl compound is filtered and then reacted with not less than 10 wt % solution of mono- or bidentate amine or phosphine ligand at 10-30°C.EFFECT: invention increases stability of production and output of chemically pure disubstituted dinitrite compounds of palladium of formula [PdL(NO)], where L is an amine (NR) or phosphine (PR) ligand, R is H and/or an organic radical.7 cl, 3 tbl, 2 ex |
