How does Primary amine undergo carbyl amine reaction? Give chemical equation.

Text Solution

Verified by Experts

Primary amines when heated with chloroform and alcoholic KoH give isoyanides having very unpleasant smell. The reaction is called as Carbylamine reaction.
` underset(1^(@) - " Amine")(R-NH_2) + underset(Alc)(CHCl_3 + 3KOH) underset("Alkyl isocyanide") overset(Delta)to R - NC + 3KCl + 3H_2O`
