ABSTRACT:
The difunctional polyfluoroaromatic compounds represented by the formula ##STR1## wherein X and Y are identical and are selected from the class consisting of --COOR.sup.1, --CH.sub.2 NH.sub.2, --CH.sub.2 NCO and ##STR2## wherein R.sup.1 is --H, alkyl and R.sup.2 and R.sup.3 independently are either --H, X or alkyl and n is either 0 or 1 are disclosed. These compounds are derived from those wherein X and Y are --CN which are produced in a solvent specific reaction. The process comprises reacting pentafluorobenzonitrile with a Grignard reagent of the formula CH.sub.3 MgHal, wherein Hal is --Cl or --Br, in the presence of either tetrahydrofuran, 1,3-dioxolane, dimethoxyethane or diglyme. When the solvent employed is tetrahydrofuran, the cyano compound wherein n is 1 is obtained. When the solvent is 1,3-dioxolane, the cyano compound wherein n is 0 is obtained.
