An easy synthetic route from substituted catechols via their corresponding aryl bistriflates to substituted phthalonitriles is described. The displacement of the triflate groups in catechol triflates by cyanide ions proceeded in high yields using zinc cyanide and palladium-1,1′-bis(diphenylphosphino)ferrocene as catalyst. The mild reaction conditions tolerate numerous functional groups and represent a desirable alternative to the generally low-yielding Rosenmund-von Braun reaction.
