Using a phosphite represented by P (x) (y) (z) (P is a phosphorus atom, x, y, z are each OR and R represents an aryl group having 18 or less carbon atoms) as a ligand, When preparing a zero valent nickel complex catalyst by reducing nickel halide to at least one metal selected from zinc, cadmium, beryllium, aluminum, iron and cobalt, the content of phosphates is 1.0 based on the total weight of phosphites. Hydrogen cyanide is added to cyanonorbornene (bicyclo [2.2.1] -5-heptene-2-carbonitrile) in the presence of a valent valent nickel complex catalyst prepared by using phosphites which are not more than% by weight. It provides a method for producing dicyano nobonane. |
