We describe herein a high yielding and metal-free methodology to access 9-aminophenanthrene derivatives and heterocyclic analogues starting from biaryl acetamides. The conversion of the substrates to their corresponding keteniminium salts triggers a spontaneous electrocyclization occurring at room temperature within a few minutes. DFT Calculations and competition reactions were carried out to rationalize
