METHOD OF PRODUCING CATIONIC COMPLEXES OF PALLADIUM WITH DIIMINE LIGANDS Russian patent published in 2015 - IPC C07F15/00 

FIELD: chemistry.

SUBSTANCE: method includes reacting a palladium complex with L in an organic solvent medium at room temperature. The used diimine ligands L are: bis[N-(phenyl)imino]acenaphthene, bis[N-(2,6-dimethylphenyl)imino]acenaphthene, bis[N-(2,6-diisopropylphenyl)imino]acenaphthene, N,N-(ethanediilidene)bis(2,6-dimethylaniline), N,N-(ethanediilidene)bis(2,6-diisopropylaniline), N,N-(2,3-butanediilidine)bis(aniline), N,N-(1,2-diphenylethane-1,2-diilidine)bis(2,6-dimethylaniline), N,N-(1,2-diphenylethane-1,2-diilidine)bis(2,6-diisopropylaniline). The process is carried out in dichloromethane as the organic solvent.

EFFECT: invention enables to obtain cationic palladium complexes which can be used as components of catalyst systems for polymerising ethylene, propylene, α-olefins and cycloolefins, copolymerising ethylene with polar vinyl monomers and cycloolefins.
