Ring-Opening Polymerization of ε-Caprolactone and Styrene Oxide-CO₂ Coupling Reactions Catalyzed by Chelated Dehydroacetic Acid-Imine Aluminum Complexes.

ABSTRACT: A series of chelated dehydroacetic acid-imine-based ligands L¹H~L⁴H was synthesized by reacting dehydroacetic acid with 2-t-butylaniline, (S)-1-phenyl-ethylamine, 4-methoxylbenzylamine, and 2-(aminoethyl)pyridine, respectively, in moderate yields. Ligands L¹H~L⁴H reacted with AlMe₃ in toluene to afford corresponding compounds AlMe₂L¹ (1), AlMe₂L² (2), AlMe₂L³ (3), and AlMe₂L⁴ (4). All the ligands and aluminum compounds were characterized by IR spectra, ¹H and ¹³C NMR spectroscopy. Additionally, the ligands L¹H~L⁴
