Direct synthesis of chiral complexes dichloro[(-)-sparteine-N,N']copper(II)
2 and dichloro[(-)sparteine-N,N']zinc(II) 3 derived from a biomolecule-nam
ely the natural base (-)-sparteine- and elemental metals (Cu and Zn) in a C
Cl4/DMSO solvent system (DMSO = dimethylsulfoxide) is reported. The complex
es were partly characterized by spectroscopic methods and their structures
were fully confirmed by single-crystal x-ray analysis. A comparison between
the new crystal structures of 2 and 3 and that of the free ligand (-)-spar
teine displayed only slight differences on the ligand framework.
