ABSTRACT:
Iodophthalonitrile is prepared by mixing aminophthalonitrile with sulfuric acid at a temperature below 25.degree. C., reacting that product with sodium nitrite at a temperature below 15.degree. C., and reacting that product with potassium iodide at a temperature below 20.degree. C. A fluoroalkyl phthalonitrile is prepared by mixing fluoroalkyl iodide, activated copper, iodophthalonitrile, and a solvent under an inert atmosphere at a temperature from 110.degree. C. to 125.degree. C. at least until the solution turns green. Both compounds are useful in synthesizing phthalocyanines and polyphthalocyanines.
