%X When 2-(2&#8242;H-benzotriazol-2&#8242;-yl)phenols containing t-alkyl substituents are warmed in toluene solution with an aluminium chloride/ nitromethane catalyst, the t-alkyl groups are transferred to the solvent (toluene). This transalkylation reaction has been used to prepare not readily accessible or previously inaccessible 2-(2&#8242;H-benzotriazol-2&#8242;- yl )phenols, a class of ultraviolet absorbers widely used in industry.
