The dichlorocarbene is :CCl2 used as an electrophile (E+) in Reimer-Tiemann reaction to give salicylaldehyde.

CHCl 3 used in the reaction to generate :CCl 2 OH -+ CHCl 3 xrightarrow[-H2O] ⊖ CCl 3 → Cl⊖+:CCl2

Q. The reaction which involves dichlorocarbene as an electrophile is,

Reimer-Tiemann reaction

Kolbe’s reaction

Friedel-Craft’s acylation

Fittig’s reaction.

The dichlorocarbene is $: CC l_{2}$ used as an electrophile $(E^{+})$ in Reimer-Tiemann reaction to give salicylaldehyde.

$C H C l_{3}$ used in the reaction to generate $: CC l_{2}$

$O H^{-} + C H C l_{3} - H_{2} O^{⊖} CC l_{3} \to C l^{⊖} + : CC l_{2}$
