Benzyl position
As the benzyl , and benzyl , is known in the organic chemistry a carbon atom in an alkylated aromatics, with a specific chemical reactivity. At least one hydrogen atom is bonded to the carbon atom in question in the alkyl radical , at the same time this carbon atom is bonded directly to the aromatic ring (e.g. a benzene ring). This hydrogen atom is easily substitutable, e.g. B. by a bromine atom in the radical bromination according to the SSS rule .
In the simplest case, the bromination of toluene produces benzyl bromide via the intermediate stage of a benzyl radical. This benzyl radical is mesomeric stabilized . One can draw four mesomeric boundary structures:
