摘要：

Substitution-, addition- and rearrangement reactions on easily available derivatives of carbohydrates (1, 2 and 4) with diphenylvinylphosphine or 2-mercaptoethyldiphenylphosphine gave chiral bidentate ethioethylphosphine ligands (5-9). These compounds form complexes with rhodium (I) in which ligands are coordinated to the metal centre by both the phosphine and the thioether function (10-12). Ligands as well as complexes were examined by Circular Dichroism (CD) spectroscopy.
