| (1S,2S)-(+)-1,2-Diaminocyclohexane Usage And Synthesis |
| 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. J Chem Soc, Chem Commun 45 1985, Takahashi et al. Tetrahedron Lett 30 7095 1989, Hanassian et al. J Org Chem 58 1991 1993, Beilstein 13 III 7.] |
