| Research Abstract |
The stereoselectivity of metal complexes has been studied:
(1) The diastereoisomers of the copper(II) and cobalt(III) complexes having the chiral Schiff-base ligand have been newly prepared and their crystal structures have been determined. The chiral Schiff-bases studied are 1-phenylethylamine(phenea), secondary-butylamine (butyl), and secondary-heptylamine(heptyl) groups. The stereoselective diastereoisomer formations were confirmed on each compound.
(2) The diastereoisomers of the copper(II) and palladium(II) complexes having the chiral monodentate primary-amine and several cyclic imidato ligands have been newly prepared and their crystal structures have been determined. The chiral amine ligands studied are 1-phenylethylamine (phenea) and secondary-butylamine(butyl). The stereoselective diastereoisomer formations were confirmed on each compound and several staggered rotamers of the phenea ligand have been found.
(3) The complexes having helical chirality were newly prepared and their crystal structures were determined. The stereoselective C-C bond formations in these systems were found. Helical trinuclear metal complexes having the ferrocene group were also prepared and, moreover, the novel metal-sulfur tetranuclear clusters were found for the metal=palladium(II) and platinum(II), respectively. From these studies, several types of the diastereoselectivity on the metal complexes were newly found and were confirmed.
