The Schiff base condensation of 8-aminoquinoline with 2-acetylcyclopentanone yielded two regioisomeric β-ketoimines with a cyclopentanyl ring in the ketoimine backbone and a pendant quinolyl moiety. The major ketoimine, isolated in 64% yield, showed quinolyl addition to the cyclopentanyl ring, and it was characterized spectroscopically and crystallographically. This ketoimine was utilized to prepare a series of bis-ligated homoleptic magnesium, aluminum, and zinc complexes in 78–96% yield as well as aluminum and zinc ketoiminate phenoxide complexes in 68 and 66% yield, respectively. The five c omplexes were characterized spectroscopically and crystallographically, and the bis-ligated complexes showed distorted octahedral geometries.
