Description

Application

(1R,2R)-(-)-1,2-Diaminocyclohexane may be used to prepare:
• Chiral C2-symmetric diphenylphosphoramide and diphenylthiophosphoramide ligands by reacting with diphenylphosphinic chloride and diphenylthiophosphinic chloride, respectively.
• Bis-urea and the amino-thiourea ligands by reacting with isocyanates and isothiocyanates, respectively.
• Biologically active chiral palladium(II) and platinum(II) complexes.

Versatile ligand for the formation of metal complexes. Used in the synthesis of chiral tropocoronands which have potential utility in asymmetric catalysis.
