Abstract
The nickel-catalyzed intermolecular coupling of allyl acetate or allyl carbonate with alkynes and alkynyltins was carried out in the presenc e of LiCl to give 3,6-dien-1-yne regio-and stereoselectively. On the o ther hand, the intramolecular cyclization and coupling of omega-alkyny l electrophiles with alkynyltins gave five-membered cyclic products. ( C) 1998 Elsevier Science Ltd.
