PHOSPHORUS TRIBROMIDE 99% (C005B-080226)

General description

Phosphorus tribromide (PBr₃) is commonly used in Hell-Volhard-Zelinsky halogenation for the α-bromination of carboxylic acids to form the corresponding acyl bromide. It is also useful for the conversion of primary and secondary alcohols to alkyl bromides.

Application

Phosphorus tribromide may be used as a reagent:

• In a novel protocol for synthesizing 7-ethoxy-1-(p-ethylphenoxy)-3,7-dimethyl-2-octene, a synthetic juvenile hormone mimic of trans,trans,cis-10,11-epoxy-7-ethyl-3,11-dimethyltrideca-2,6-dienoate.
• To synthesize 1,2,3-diazaphosphinane, 1,2,3-thiazaphosphinine and 1,2-azaphosphole bearing a chromone ring.
• To synthesize 1-Bromoundec-1-ene from 10-undecen-1-ol.
