FIELD: chemistry.
SUBSTANCE: invention relates to catalytic systems based on organophosphorous compounds, complex-forming, suitable for hydrocyanation and hydroformylation of alkenes of formulas M[Lf]t(V) or HM[Lf]t+nCO4-n(VI), where M is transition metal, t is number from 1 to 10, n is number from 1 to 4, Lf stands for organofosphorous ligand of formulas:
or 
,
where R1, R2, R3, R4, R5, R7, Z stand for hydrogen atom, C1-12alkyl, phenyl, optionally substituted with 1-3 substituents, selected from C1-6-alkyl and hydroxy-C1-6-alkyl, or C1-12halogenalkyl; X, X1 and X2 stand for O or S, R6 stands for covalent bond, C6-aryl or several bound C6-aromatic cycles, n and n1, stand for valence X1, X2, reduced by 2.
EFFECT: claimed are novel effective catalysts of hydrocyanation and hydroformylation.
