white to light yellow crystal powder | [Uses]
(1R,2R)-(-)-1,2-Diaminocyclohexane can be used as a building block for chiral ligands.
| [Uses]
suzuki reaction | [Purification Methods]
Distil or recrystallise the diamine from pet ether under N2 or Ar. Store it as above. The 1R,2R-base L-tartrate salt has M 264.3, m 2 7 3o and [ ] D +12.5o (c 4, H2O), and can be used to purfy and/or optically enrich the free base. [Beilstein 13 III 6, and references below.] |
