Method for producing transition metal-isocyanide complex

A method for producing a transition metal-isocyanide complex represented by formula (2) below,

• the method comprising reacting together a compound containing a transition metal selected from V, Cr, Mo, W, Fe, Ru, Co, Rh, Ni, Pd, and Pt, and an isocyanide compound represented by formula (1) below in the presence of an alkali metal supported by a solid substance insoluble in an organic solvent,
• (CN)x—R1 (1)
• wherein R1 represents a monovalent to trivalent organic group that has 1 to 30 carbon atoms and is optionally substituted with a halogen atom and in which one or more atoms selected from oxygen, nitrogen, sulfur, and silicon are optionally interposed, and x represents an integer of 1 to 3,
• M1a(L)b (2)
• wherein M1 represents V, Cr, Mo, W, Fe, Ru, Co, Rh, Ni, Pd, or Pt with an oxidation number of zero, L represents an isocyanide compound represented by the formula (1), M1 may be the same or different, and L may be the same or different, “a” represents an integer of 1 to 8, and “b” represents an integer of 2 to 12, and
• wherein the solid substance insoluble in an organic solvent is at least one selected from a carbon material, a silicon compound, a metal oxide, and a polymer compound.
