FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing compounds which contain at least one nitrile functional group via hydrocyanation of an organic compound containing 2-20 carbon atoms and at least one unconjugated unsaturated bond, on a reaction with hydrogen cyanide in the presence of a catalyst system. The catalyst system contains a complex of nickel in zero oxidation state with at least one organophosphorus ligand selected from a group comprising organophosphites, organophosphonites, organophosphinites and organophosphines, and a cocatalyst. The method is characterised by that the cocatalyst is an organometallic compound of general formula 
(I). In formula (I) R1, R2, R3 are alkyl radicals containing 1-6 carbon atoms, substituted or unsubstituted phenyl radicals or halogen atoms; M1 and M2, identical or different, denote elements with valence m1 and m2, respectively, selected from a group comprising zinc, boron, aluminium, cadmium, gallium, indium and tin, wherein M1 and M2 cannot be boron at the same time; X is an element with valence x, selected from a group comprising oxygen, carbon, nitrogen, silicon, sulphur and phosphorus; n is an integer equal to m1-1; p is an integer equal to m2-1; t is an integer equal to x-2.
EFFECT: method enables to achieve acceptable values of linearity of obtained nitriles.
