O-Benzylhydroxylamine hydrochloride Chemical Properties,Usage,Production
Chemical Properties
white to light yellow crystal powde
Uses
For use in the formation of nitrones from carbonyl compounds and their use in cycloaddition reactions. Used as a reagent used in the synthesis of hydroxylamines and hydroxyamates. Effective reagent used to prepare α-hydroxybenzylamines from α-hydroxyketones.
Uses
O-Benzylhydroxylamine hydrochloride is a reagent used for the synthesis of hydroxylamines and hydroxyamates.
Synthesis
Add the O-benzylacetoxime to a mixed solution of 17 g of methanol and 200 g of a 38% mass concentration hydrochloric acid solution; react for 210 minutes at a temperature of 36°C and a stirring speed of 90 rpm; then distill under reduced pressure at a temperature of 65°C until a solid precipitate out, and cool to room temperature. The solid was washed with petroleum ether (100mL×3) and dried under vacuum at 80°C for 8 hours to obtain 95.18g of the target product O-Benzylhydroxylamine hydrochloride, with a purity of 99.87%; the yield is 98.72%.
Purification Methods
Recrystallise the hydrochloride from H2O or EtOH. [Beilstein 6 IV 2562.]
