What is PBr3 in chemistry?
Correspondingly, what is PBr3 used for?
The main use for phosphorus tribromide is for conversion of primary or secondary alcohols to alkyl bromides, as described above. PBr3 usually gives higher yields than hydrobromic acid, and it avoids problems of carbocation rearrangement- for example even neopentyl bromide can be made from the alcohol in 60% yield.
Also Know, what is the name for PBr3? Chemical structure: Other names: PBr3; Phosphorus(III) bromide; Phosphorous tribromide; Extrema; Phosphorous bromide; Phosphorus bromide; Tribromophosphine; UN 1808; Phosphorus bromide (PBr3)
Furthermore, what is PBr3 in organic chemistry?
If the alcohol is primary or secondary, the reagent of choice is phosphorous tribromide (PBr3). If the alcohol is tertiary, we use hydrogen bromide (HBr) to ake the alkyl halide. The situation is similar if we wish to make an alkyl chloride.
