PHOSPHINYL AMIDINE COMPOUNDS, METAL-CONTAINING COMPLEXES, CATALYTIC SYSTEMS AND THEREOF APPLICATION FOR OLIGOMERISATION OR POLYMERISATION OF OLEFINS Russian patent published in 2015 - IPC C07F9/46 C07F11/00 C08G61/04 C08F4/78 

FIELD: chemistry.

SUBSTANCE: claimed invention relates to phosphonylamidines and metal-containing complexes on their basis for obtaining catalysts for oligomerisation of olefins, of formulae: and , respectively, where: R¹ represents C₁-C₁₅ alkyl, C₄-C₂₀ cycloalkyl, C₄-C₂₀ substituted cycloalkyl, C₆-C₂₀ aryl or C₆-C₂₀ substituted aryl, R² represents C₁-C₁₅ alkyl, C₄-C₂₀ cycloalkyl, C₄-C₂₀ substituted cycloalkyl, C₆-C₂₀ aryl, C₆-C₂₀ substituted aryl, C₇-C₂₀ aralkyl or C₇-C₂₀ substituted aralkyl, R³ represents hydrogen, and each R⁴ and R⁵ independently represents C₁-C₁₅ alkyl, C₄-C₂₀ cycloalkyl, C₄-C₂₀ substituted cycloalkyl, C₆-C₂₀ aryl, C₆-C₂₀ substituted aryl, where each substituent represents halogenide, C₁-C₁₀ alkyl or C₁-C₁₀ alkoxygroup, MX_P represents metal salt, where M represents chrome, cobalt or nickel, X represents halogen, and p constitutes from 2 to 6, Q represents neutral ligand, where each ligand, independently represents C₂-C₂₀ nitrile or C₂-C₂₀ether, and a constitutes from 0 to 3.

EFFECT: claimed are novel effective catalysts for oligomerisation of olefins and methods of obtaining thereof.
