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.

SpletAn efficient conversion of alcohols and β-amino alcohols to the corresponding chlorides can be carried out at room temperature in methylene chloride, using 2,4,6-trichloro [1,3,5]triazine and N,N -dimethyl formamide. Addition of NaBr allows the synthesis of bromides. Optically active carbinols react under inversion. SpletPBr 3 Phosphorus tribromide ( PBr3) is possibly the most common reagent for the bromination of alcohols. The mechanism occurs by SN2 and results in the inversion of …

Splet06. mar. 2024 · The HBr route goes through a carbocation which scrambles the stereochemistry completely. PBr3 will invert the stereochemistry, then SN2 -CN addition will invert it again, giving you the wrong product. You need something that turns the -OH group into a leaving group while preserving the stereochemistry, so that the CN can displace it …
