摘要

Four aluminum alkyl compounds, [CH{(CH₃)CN-2,4,6-MeC₆H₂}₂AlMe₂] (1), [CH{(CH₃)CN-2,4,6-MeC₆H₂}₂AlEt₂] (2), [CH{(CH₃)CN-2-iPrC₆H₄}₂AlMe₂] (3), and [CH{(CH₃)CN-2-iPrC₆H₄}₂AlEt₂] (4), bearing β-diketiminate ligands [CH{(Me)CN-2,4,6-MeC₆H₂}]₂ (L¹H) and [CH{(Me)CN-2-ⁱPrC₆H₄}]₂ (L²H) were obtained from the reactions of trimethylaluminum, triethylaluminum with the corresponding β-diketiminate, respectively. All compounds were characterized by ¹H NMR and ¹³C NMR spectroscopy, single-crystal X-ray structural analysis, and elemental analysis. Compounds 1–4 were found to catalyze the ring-opening polymerization (ROP) of ε-caprolactone (ε-CL) with good activity.
