The stoichiometric reactions of 8-(2,6-R¹-4-R²-anilide)-5,6,7-trihydroquinoline () with AlR₃ (R = Me or Et) afforded the aluminum complexes (⁻,: R¹ = Pr, R² = H, R = Me; : R¹ = Me, R² = H, R = Me; : R¹ = H, R² = H, R = Me; : R¹ = Me, R² = Me, R = Me; : R¹ = Me, R² = Me, R = Et) in high yields. All aluminum complexes were characterized by NMR spectroscopy and elemental analysis. The molecular structures of complexes and were determined by single-crystal X-ray diffractions and revealed a distorted tetrahedral geometry at aluminum. In the presence of BnOH, complexes ⁻ efficiently initiated the ring-opening homopolymerization of -caprolactone (-CL) and -lactide (-LA), respectively, in a living/controlled manner.
8-(2,6-R¹-4-R²-苯胺基)-5,6,7-三氢喹啉（）与AlR₃（R = 甲基或乙基）的化学计量反应以高产率得到铝配合物（⁻，：R¹ = 丙基，R² = 氢，R = 甲基；：R¹ = 甲基，R² = 氢，R = 甲基；：R¹ = 氢，R² = 氢，R = 甲基；：R¹ = 甲基，R² = 甲基，R = 甲基；：R¹ = 甲基，R² = 甲基，R = 乙基）。所有铝配合物均通过核磁共振光谱和元素分析进行表征。配合物和的分子结构通过单晶X射线衍射确定，并揭示了铝处扭曲的四面体几何结构。在苄醇存在下，配合物⁻分别以活性/可控方式有效地引发了己内酯（-CL）和丙交酯（-LA）的开环均聚反应。
