Reimer-Tiemann reaction

Explain the following with an example.

Reimer-Tiemann reaction

Chemical Equations/Structures
Explain

Solution 1

On treating phenol with chloroform in the presence of sodium hydroxide, a –CHO group is introduced at ortho position of benzene ring. This reaction is known as Reimer-Tiemann reaction. The intermediate substituted benzal chloride is hydrolysed in the presence of alkali to produce salicylaldehyde.
