Alkyne metathesis: Toward simplicity and efficiency

Maraval, Valérie,Lepetit, Christine,Caminade, Anne-Marie,Majoral, Jean-Pierre,Chauvin, Remi

, p. 2155 - 2159 (2006)

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 9-24 h, and the symmetrical alkyne is produced in ca. 95% yield.
