FIELD: organic chemistry, catalysts.
SUBSTANCE: invention relates to method for hydrocyanation of olefins containing at least one ethylenically unsaturated bond by reaction thereof with hydrogen cyanide in presence of catalytic system comprising transition metal and organophosphorous ligand of formula I 
, followed by isomerization of formed nitrile compound. In formula: R1 and R2 are hydrogen atom; R4, R5 and R6 are independently aliphatic, unsaturated C1-C40-hydrocarbon radical, or carbocyclic aromatic hydrocarbon radical; R3 is X radical, wherein X is selected from carbocyclic aromatic monocyclic radical; R7 is aromatic hydrocarbon radical or hydrocarbon radical containing aldehyde group.
EFFECT: catalytic system of improved catalytic activity and stability.
