| description | FIELD: organic synthesis catalysts. SUBSTANCE: invention relates to production of catalysts for synthesis of adiponitrile and describes catalyst comprising at least one complex of VIII secondary group c with at least one bidentate phosphonite ligand of general formula I (represented in description) or their salts and mixtures. Described are also production of mixtures of monoolefin mononitriles with 5 carbon atoms, catalytic isomerization of branched aliphatic monoalkennitriles, and production of adiponitrile. EFFECT: increased selectivity and catalytic activity in hydrocyanation of 1,3- butadiene and hydrocarbon mixtures. 8 cl, 3 tbl, 4 ex |
