Reimer-Tiemann reaction

Vedclass · Answer

(B) The Reimer-Tiemann reaction involves the introduction of a formyl group $(-CHO)$ into the benzene ring of phenol using chloroform $(CHCl_3)$ and aqueous $NaOH$. This process involves the formation of a new carbon$-$carbon bond between the aromatic ring and the formyl carbon. The reaction is represented as: Phenol + $CHCl_3$ $\xrightarrow{NaOH, 340 K}$ Salicylaldehyde (via intermediate) $\xrightarrow{dil. HCl, -NaCl}$ Salicylaldehyde. Therefore,the correct option is $(B)$.

In which of the following reactions does carbon$-$carbon bond formation take place?
