METHOD OF OBTAINING DIFFERENT-LIGAND CATIONIC COMPLEXES OF PALLADIUM Russian patent published in 2011 - IPC C07F15/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing different-ligand cationic complexes of palladium which contain organic and elemento-organic ligands of general formula [(L¹)Pd(L²)(L³)]A. The method involves reaction of a palladium complex with electron-donor ligands and boron trifluoride etherate BF₃OEt₂ and a strong Bronsted acid with a weakly coordinating anion of the HA type, where A=BF₄. The palladium complex used is Pd(Acac)₂·PPh₃ and the electron-donor ligands used are trialkyl phosphines of the PR₃ type or secondary amines of the HNR'₂ type, where R' is ethyl or butyl. L¹ is acetylacetonate (acac), L² is PPh₃, L³ denotes secondary amines such as diethylamine, dibutylamine or trialkylphosphines, for example tricyclohexylphosphine or tributylphosphine. The process is carried out in a benzene or toluene medium, used as organic solvent at temperature 15-30°C.

EFFECT: obtaining cationic complexes of palladium of the [(L¹)Pd(L²)(L³)]BF₄ type in a single step.
