Abstract

Homo-chiral Cu(II) complexe with C1 symmetric ligands was synthesized and characterised. The X-ray crystal structure of Cu(II) complex containing these ligands were determined. The geometric shapes around the center of Cu (II) for all LCuCl2 were distorted into squares. Catalytic activities of LCuCl2 and LCu(OAc)2 with 10 mol% of diisopropylethylamine in the asymmetric Henry reaction of aldehyde(benz-, 3-phenylpropion-, isovaler-, n-butyl-) and nitro-mthane was examined.
