What is Regioselective Gomberg-Bachmann Reaction about?

This document describes the synthesis of 7-arylquinolinones and 6-arylindoles from 3-aminobiphenyls. 3-Aminobiphenyls were obtained in good yields from 4-anisidine and various aryl diazonium salts through a titanium-mediated radical arylation reaction. 7-Arylquinolinones were synthesized in two steps by first converting the 3-aminobiphenyls into cinnamic amides, which then underwent a highly regioselective cyclization under phosphoric acid and phosphorus pentoxide to eliminate anisole. 6-Arylindoles were al
