Using phenol how can we prepare salicylaldehyde? I hope we all are familiar with the reaction named Reimer-Tiemann reaction. Here note that phenol when heated with chloroform & NaOH at 60 degree Celsius & on acidifying the product obtained, salicylaldehyde is formed.
Also remember that if carbontetrachloride is used instead of chloroform, the product obtained is salicylic acid.
