METHOD FOR CARBONYLATION WITH ADDITION OF STERICALLY HINDERED SECONDARY AMINES Russian patent published in 2012 - IPC C07C45/50 C07C47/02 B01J31/02 B01J31/18 B01J23/24 C07C23/40 B01J23/74 

FIELD: chemistry.

SUBSTANCE: invention relates to a carbonylation method in which at least one compound olefinically unsaturated compound reacts with carbon monoxide in the presence of a complex catalyst of a metal of subgroup VIII of the periodic table of elements, containing an organophosphorus compound as a ligand, where the additional reagent used is at least hydrogen and hydroformylation is carried out. Carbonylation is carried out in the presence of at least one sterically hindered secondary amine with 2,2,6,6-tetramethylpiperidine , units. The invention also relates to a mixture for use in the disclosed carbonylation method.

EFFECT: invention enables to obtain desired products with high selectivity using a stable catalyst system.
