Efficient synthesis of biindenylidene derivatives via a domino-Heck-type double cyclization of diaryldienynes.
[reaction: see text] Synthesis of aromatic ring substituted (E)-1,1'-biindenylidene derivatives was achieved by a domino-Heck type double cyclization of (Z,Z)-1,6-diaryl-1,5-hexadien-3-ynes.
