Lanthanide Schiff-base complexes with the formula [3,5-tBu 2 -2-(O)C 6 H 2 CH=NC 6 H 5 ] 3 Ln(THF) (Ln = Sc, Y, La, Nd, and Gd) were synthesized by the metathesis reaction of anhydrous LnCl 3 with a Schiff-base sodium salt in good yields (> 80%). The complex containing a neodymium center was charact

Asymmetric cyclopropanation of olefins was carried out with chiral copper-Schiff base complexes derived from copper acetate monohydrate, substituted salicylaldehydes and a chiral amino alcohol. Substituents on salicylaldehyde framework demonstrate a significant effect on the steroselectivities. Thos
The oxygenation of styrene catalyzed by optically active cobalt Schiff base complexes in 2-propanol gives an enantiomer excess of l-phenylethanol. The asymmetric induction may be accomplished in two steps: addition of CoH species to styrene and decomposition of 1-phenylethyl hydroperoxide. Cobalt Sc
