A direct oxidative cyanation of arenes under FeII catalysis with 3,5‐di(trifluoromethyl)phenyl(cyano)iodonium triflate (DFCT) as the cyanating agent has been developed. The reaction is applicable to wide range of aromatic substrates, including polycyclic structures and heteroaromatic compounds.

combination of the recently developed multicomponent construction of highly substituted 3,4-dihydropyridones with subsequent allylation and intramolecular Heck-type cyclization allows the straightforward construction of benzo[a]quinolizines, a class of polycyclic compounds that – despite their interesting pharmacological and photochemical properties – have little precedent in the literature.
