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.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
