(+/-)-trans-1,2-Diaminocyclohexane Usage And Synthesis

Chemical Properties	clear colorless to light yellow liquid
Uses	(^+)-trans-1,2-Diaminocyclohexane is employed in the synthesis of macrocyclic [3+3] hexa Schiff base. It also plays an important role in the preparation of multidentate ligands, chiral auxiliaries and chiral stationary phases. Further, it is used to prepare [2+2] macrocyclization by reacting with aliphatic dialdehydes. In addition to this, it acts as a chiral ligand, which finds application in asymmetric catalysis.
Uses	(±)-trans-1,2-Diaminocyclohexane was used in the synthesis of macrocyclic [3+3] hexa Schiff base. It was also employed in the synthesis of multidentate ligands, chiral auxiliaries and chiral stationary phases.
General Description	(±)-trans-1,2-Diaminocyclohexane was condensed with aliphatic dialdehydes to form [3+3] or [2+2] macrocyclization products.
Purification Methods	Purify and store the diamine as for the cis-isomer above as it is a strong base and becomes yellow on storage. [Beilstein 13 IV 1.]
