Abstract

Cationic ruthenium porphyrin complex was found to be an efficient catalyst for the Friedel–Crafts type reaction of arenes with imines. The use of a structurally rigid tetradentate porphyrin as the equatorial ligand and weakly coordinating axial ligand is the key to bring out the catalytic reactivity of ruthenium for the reaction.
