Abstract
3, 3′-Disubstituted 2, 2′-binaphthyls were prepared by the Cuor Re-catalyzed double benzannulation reaction of 2-(phenylethynyl) benzaldehyde with various butadiynes in the presence of trichloroacetic acid, in moderate to good yields. Acceleration of the second benzannulation was clearly observed.
