(a) Benzoin condensation : Heating ethanolic solution with strong alkali like KCN or NaCN, benzoin is obtained.
(b) Formation of phenolphthalein phenol is treated with phthalic anhydride in the presence of conc. ${\mathrm{H}}_2{\mathrm{SO}}_4$, it gives phenolphthalein, an indicator.
(c) Fries rearrangement Phenyl benzoate heated with anhydrous ${\mathrm{AlCI}}_3$ in the presence of inert solvent gives ortho-and Para-hydroxybenzophen one. In this rearrangement, there is only a benzoyl group migration from the phenolic oxygen to an ortho-and para-position.
(d) Methylsalicylate
(A chief constituent of oil of wintergreen)
