Answer
Reimer-Tiemann reaction:
When phenol is treated with chloroform $(CHCl_3)$ in the presence of sodium hydroxide, a - CHO group is introduced at the ortho position of the benzene ring.
This reaction is known as the Reimer-Tiemann reaction. The intermediate is hydrolyzed in the presence of alkalis to produce salicyclaldehyde.
