CROTYL BROMIDE TECH. 85 Chemical Properties,Usage,Production

Chemical Properties

clear light yellow to yellow-brown liquid

Uses

Crotyl bromide is a general organic reagent that can be used in the total synthesis of biologically important natural products and their derivatives such as (+)-artemisinin, plakortone E and (?)-horsfiline.
It can also be used to prepare analogs of deoxycyclitols, pentopyranoses, 6-deoxyhexoses, hexoses and pseudo-indoxyl derivatives.

Purification Methods

Dry the bromide with MgSO4/CaCO3 mixture and fractionally distil it through an all-glass Todd column (p 11). [Beilstein 1 IV 789.]
