Chemical Properties

white to light yellow crystal powder

Uses

suzuki reaction

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.
