The displacement of all six fluorine atoms from hexafluorobenzene by sodium cyanide in methanol
Abstract
A by-product from the reaction of pentafluorobenzonitrile or hexafluorobenzene with sodium cyanide in methanol has been identified as 1,4-dicyano-2,3,5,6-tetramethoxybenzene. Its formation from hexafluorobenzene involves the displacement of all six fluorine atoms.
