Abstract
AbstractA family of aluminum complexes containing anilido‐oxazolinate ligands are described. Reactions of five anilido‐oxazolinate ligand precursors, HNPhTriMeOxa, HNPhDiiPrOxa, HNPhOMeOxa, HNPhSMeOxa, or HNPhOxa, with 1 molar equiv. of AlMe3 in toluene give the aluminum dimethyl complexes (NArOxa)AlMe2 [Ar = 2,4,6‐trimethylphenyl, (NPhTriMeOxa)AlMe2 (1); Ar = 2,6‐diisopropylphenyl, (NPhDiiPrOxa)AlMe2 (2); Ar = 2‐methoxyphenyl, (NPhOMeOxa)AlMe2 (3); Ar = 2‐methylthiophenyl, (NPhSMeOxa)AlMe2 (4); Ar = phenyl, (NPhOxa)AlMe2 (5), respectively]. The molecular structures are reported for compounds 1–4. Their catalytic activities toward the ring‐opening polymerization reactions of L‐lactide or ϵ‐caprolactone in the presence of BnOH are also under investigation. (© Wiley‐VCH Verlag GmbH & Co.
