Benzyl bromide : C7H7Br

This is organic compound subsist of a benzene ring substituted with a bromomethyl group. ( Benzyl bromide, or α-bromotoluene ) It can be set-up by the bromination of toluene at room temperature in air , using manganese oxide as a unrelated catalyst . It is a colorless liquid that is turn out slowly in water.

α-bromotoluene/Benzyl bromide is used in elemental integration for the introduction of  the benzyl protecting group for alcohols and carboxylic acids.
