(Chemical Equation Presented) Alkynyldimethylaluminum reagents are easily available from terminal akynes and trimethylaluminum via a triethylamine- catalyzed metalation. These compounds can react with various aromatic and heterocyclic halides in the presence of palladium in a fast and efficient way. This catalyzed cross-coupling reaction provides a simple entry to numerous internal alkynes, using a readily available, inexpensive, and nontoxic metalating agent.

The synthesis of Poly(1-phenyl-7-aryl-1, 6-heptadiyne) by Cyclopolymerizations of asymmetrically α, ω distributed alkadiynes was discussed. The alkadiynes were prepared by a synthetic route involving consecutive palladium-catalyzed cross coupling reactions. Substitution of the olefinic hydrogen in cyclic polyene by an aromatic ring was used for the polymer stability. It was found that the polymer stability increases with a decrease in the number of the active hydrogen atoms.
