Abstract

Cyanation of aryl chlorides with potassium hexacyano­ferrate(II) catalyzed by cyclopalladated ferrocenylimine tricyclohexylphosphine complex has been described. This method is applicable to both activated and deactivated aryl chlorides. The ­corresponding aryl nitriles were isolated in good to excellent yields

Key words

cyclopalladium - cyanation - aryl chloride - catalysis - coupling
