Abstract: Palladium-catalyzed Suzuki-Miyaura cross-coupling of 2-aryl-4-azido-3-iodo-quinolines with arylboronic acids afforded the corresponding primary 4-amino-2,3-diarylquinolines in a single-pot operation along with symmetrical biaryls and traces of the 2,3-diaryl-4-azidoquinolines. A plausible mechanism, which implicates palladium hydride species in the reduction of the incipient 2,3-diaryl-4-azidoquinolines to afford the 4-amino-2,3-diarylquinolines is proposed.
Keywords: 2-aryl-4-azido-3-iodoquinolines; Suzuki-Miyaura cross-coupling; symmetrical biaryls; 4-azido-2,3-diarylquinolines; 4-amino-2,3-diarylquinolines
