摘要

No catalyst pre-activation, no suicide alkyne, and no additive is required in an extremely simple procedure for the metathesis of alkyl-, alkenyl-, and aryl-propynes: just mix Mo (CO) 6, p-chlorophenol, and the alkyne in 1, 2-dichloroethane, heat at 85° C for 9–24h, and the symmetrical alkyne is produced in ca. 95% yield.
