Gold‐Catalyzed Cyclizations of Alkynes with Alkenes and Arenes

Abstract This chapter reviews the gold‐catalyzed cyclization reactions of alkynes with alkenes that proceed via selective activation of the alkyne by π‐coordination of the transition metal. Mechanistically related intermolecular reactions between alkynes and alkenes are also discussed, as are reactions of alkynes with arenes, heteroarenes, and related nucleophiles.
