The nickel-catalyzed intermolecular coupling of allyl acetate or allyl carbonate with alkynes and alkynyltins was carried out in the presence of LiCl to give 3,6-dien-1-yne regio- and stereoselectively. On the other hand, the intramolecular cyclization and coupling of ω-alkynyl electrophiles with alkynyltins gave five-membered cyclic products.
