(1S,2S)-(+)-1,2-Diaminocyclohexane Chemical Properties,Uses,Production

Chemical Properties

white to light yellow crystal powder

Uses

suzuki reaction

Uses

For synthesis of optically active products

Uses

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

Purification Methods

Distil or recrystallise the diamine from pet ether under N2 or Ar. Store it as above. The 1S,2S-base D-tartrate salt has M 264.3, m 180 -1 8 4o(dec) and [] 25 -12.5o (c 4, H2O) from which the free base can be purified or optically enriched. It is a useful chiral synthon. [Fjii et al.
