Abstract
PURPOSE: To obtain the title compound usable as raw materials for adhesives and heat-resistant resins industrially advantageously, by reacting a polyhalogenated benzene with an inorganic cyano compound in the presence of cupric ions in a polar organic solvent.
CONSTITUTION: A polyhalogenated benzene of formula I: (X is Cl, Br, or I; R is H or methyl group; n is an integer 3W6), e.g. 1,2,4,5-tetrachlorobenzene, is reacted with an inorganic cyano compound, e.g. sodium cyanide, in the presence of cupric ions, e.g. cupric sulfate, in a polar organic solvent to give a compound of formula II. An amide solvent, preferably N-methyl-pyrrolidone, may be cited as the polar organic solvent.
