Abstract

(Chemical Equation Presented) A rhenium complex, [ReBr(CO) ₃(thf)]₂, catalyzed the intermolecular reactions of 1,3-dicarbonyl compounds with terminal acetylenes and gave the corresponding alkenyl derivatives in excellent yields. These reactions could apply to an intramolecular version and gave the corresponding cyclic compounds quantitatively.
