Mo(CO)_6催化炔烃三聚制备苯衍生物

Mo(CO)_6 Catalyzed Cyclotrimerization of Alkynes: Formation of Benzene Derivatives

Mo(CO)6催化炔烃三聚制备了苯系衍生物,并对催化剂用量和不同溶剂对产物收率的影响进行了考察,推测了可能的催化反应机理.

Mo（CO）6 performed good catalytic activity of the cyclotrimerization of terminal- or intemalalkynes as well as the alkynes with either electron-donating or electron-withdrawing groups to form trisubstituted or hexasubstituted benzene derivatives. The effect of solvent and amount of catalyst on the yield of benzene derivatives were investigated, indicating that the reaction proceeded smoothly in toluene with 15% Mo（CO）6.
