What happens when phenol reacts with CHCl3 and NaOH?

What happens when phenol reacts with CHCl3 and NaOH?

Phenol on heating with CHCl3 and NaOH gives salicylaldehyde.

Does NaOH dissolve in CHCl3?

It is not necessary (and impossible anyway) to dissolve the sodium hydroxide in chloroform. In all cases, powdered NaOH is added to a mixture of the phenol derivative and the ketone, and then the chloroform is added in the final step. So don’t worry about “dissolving” NaOH in chloroform.

What is the reactive intermediate from reaction between CHCl3 and NaOH?

Phenol on, reaction with CHCl3 and NaOH gives sailcylaldehyde.
