21. When phenylacetylene was used as the reaction partner instead of aliphatic acetylenes, a dimerization reaction of phenylacetylene occurred giving (E)-1,4-diphenylbut-1-en-3-yne in 45% yield. On the other hand, when acyclic amides were used instead, of cyclic amide, the reaction did not occur and the amide was recovered almost quantitatively.
22. The substrate was synthesized following the procedure in ref 8a.
