white to light yellow crystal powde | [Uses]
(R)-(-)-1-Phenyl-1,2-ethanediol is an intermediate for the synthesis of enantiopure substituted 1,4-Dioxanes. Extremely valuable and versatile alcohol used as a chiral building block in organic synthesis.
| [Uses]
Intermediate for the synthesis of chiral phosphine catalysts for asymmetric hydrogenations. | [Purification Methods]
Purify the diol by recrystallisation from *C6H6/ligroin and sublime it at 1-2mm. [Arpesella et al. Gazetta 85 1354 1955, Prelog et al. Helv Chim Acta 37 221 1954, Beilstein 6 IV 5939.] |
