摘　　要：在茂基上引入一个酯基官能团,合成了一类新型的茂基金属铑催化剂.此催化剂被应用于催化芳基肟与炔的碳氢活化[4+2]环加成合成四氢异喹啉的反应中.结果表明,该催化剂在反应活性以及醋酸盐用量方面都优越于常规催化剂[Cp^(*)RhCl_(2)]_(2).A new type of cyclopentadienyl metal rhodium catalyst was synthesized by introducing an ester functional group onto the cyclopentadienyl group.The catalyst was evaluated with C—H active[4+2]annulation of aryl oximes and alkynes.The result demonstrated that the new catalyst was superior to conventional catalysts[Cp^(*)RhCl_(2)]_(2) in terms of reactivity and the usage of the metal acetate added.
