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.

The tungsten benzylidyne complex [PhC≡W{OSi(OtBu)3} 3] (1) efficiently catalyses the metathetic conversion between symmetrical and unsymmetrical 1,3-diynes, which provides the opportunity to prepare the latter species directly from terminal alkynes by a combination of copper-catalysed homocoupling and catalytic alkyne cross-metathesis (ACM).
