FIELD: organic chemistry.
SUBSTANCE: claimed method includes reaction of diolefinic compounds or compounds containing at least one ethylenic bond and cyano group with hydrocyanic acid in presence of catalytic system containing nickel compound, bound with organophosphorus ligands selected from group including organophosphonites, organophosphinites, organophosphites, organophosphines, and organophosphoramidites, wherein said ligands represent mixture containing at least first ligand, selected from group of monodentate organophosphites of general formula I 
(wherein R1, R2, R3 are independently linear or branched C1-C12-alkyl optionally containing heteroatom, optionally substituted aromatic or cycloaliphatic radical, optionally containing heteroatoms, optionally substituted aromatic or cycloaliphatic radical, optionally containing heteroatoms and one ore more optionally condensed rings; or R1, R2, R3, may be bound to by to), and at least second ligand selected from group containing bidentate organophosphorus ligans of general formula II 
(wherein R1, R2, R3, R4 are independently linear or branched C1-C12-alkyl optionally containing heteroatom, optionally substituted aromatic or cycloaliphatic radical, optionally containing heteroatoms and one ore more optionally condensed rings; or R1 and R2 and/or R3 and R4 may be bond together; X1, X2, X3, X4, X5, X6 are independently covalent bond, oxygen atom or divalent radical -NR5-, wherein R5 represents hydrogen atom or alkyl, aryl, sulfonyl, cycloalkyl or carmonyl radical; L is covalent bond or divalent linear C1-C12-alkyl optionally containing heteroatoms, divalent optionally substituted aromatic or cycloaliphatic radical, optionally containing heteroatoms and one ore more optionally condensed rings, divalent alkylaryl or arylalkyl radical). Also disclosed is method for hydrocyanating of nitryle ethylenically unsaturated compounds under abovementiones conditions including addition cocatalyst in catalytic system. Said cocatalyst contains at least one Lewis acid.
EFFECT: bidentate compounds with improved stability in reaction medium without losses of catalytic properties such as selectivity.
