Abstract
Treatment of two classes of oxazolinyl-indolate ligand precursors with an equivalent trimethylaluminum reagent afforded four corresponding aluminum dimethyl complexes. Intramolecular functional groups were employed to switch coordination behaviors, resulting in the formation of two classes of five- or six-membered aluminum metallocyclic complexes. The screening of the prepared aluminum complexes, mediated by 9-anthracenemethanol as the initiating reagent in the ring-opening polymerization of ε-caprolactone, showed significant activities at room temperature. The aluminum compound ligated by 2-(1H-indol-2-yl)-4,4-dimethyl-4,5-dihydrooxazole possessed a suitable chelated ring size, and its intrinsic electronic properties maintained higher activity.
期刊介绍：
All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
