Abstract

A series of ketoimines bearing quinolyl pendants was prepared through Schiff base condensation of 1,3-diketones (2,4-pentanedione, benzoylmethane, and 1-benzoylacetone) and 8-aminoquinoline or 8-amino-2-methylquinoline. The ketoimines were isolated in 46-90% yield and characterized spectroscopically and crystallographically. Reaction of the ketoimines with magnesium 4-methylbenzylalkoxide yielded octahedral magnesium complexes in 67-90% yield. The spectroscopic and crystallographic properties of the magnesium complexes were explored. Structures of 1, 4, 8, 10, and 11 are reported.
