[Ir(cod)Cl] 2 in combination with 1,2-bis(dipentafluorophenylphosphino)ethane catalyzes chemo- and regioselective cyclotrimerization of two different alkynes. The reaction of methyl propiolate with 1-hexyne gave methyl 3,5-di( N-butyl)benzoate as a single product in 88% yield.
[Ir(cod)Cl] 2 与 1,2-双(二五氟苯基膦基)乙烷结合催化两种不同炔烃的化学和区域选择性环三聚反应。丙炔酸甲酯与 1-己炔反应以 88% 的产率得到 3,5-二(N-丁基)苯甲酸甲酯作为单一产物。
