AbstractA process1for the synthesis ofortho‐bromo aromatic compounds was studied. The process is based on the blocking and shielding effect of a tertiary butyl group which is introduced on to the aromatic ring prior to bromination. The removal of the tertiary butyl group, after bromination, is accomplished by transferring it to another aromatic nucleus via an aluminium trichloride catalysed transalkylation reaction. Synthesis of six different compounds are described and a recycle process is illustrate
