Vedclass · Answer

(A) The reaction described is the $Reimer-Tiemann$ reaction.
In this reaction,phenol reacts with chloroform $(CHCl_3)$ in the presence of an aqueous base $(NaOH)$ to form $o$-hydroxybenzaldehyde (salicylaldehyde).
The electrophile involved in this reaction is dichlorocarbene $(:CCl_2)$,which is generated from chloroform by the action of the base.
The mechanism is as follows:
$OH^{-} + CHCl_3 ightleftharpoons H_2O + :CCl_3^{-} 	o Cl^{-} + :CCl_2$ (dichlorocarbene).

The reaction of phenol with chloroform and sodium hydroxide to give $o$-hydroxybenzaldehyde involves the formation of which intermediate?
