Which organic reaction involves the conversion of a primary amine into an isocyanide (carbylamine) by heating with chloroform and alcoholic potassium hydroxide?

💡 Solution & Explanation

The carbylamine reaction is a definitive chemical test for identifying primary amines by heating them with chloroform and alcoholic potassium hydroxide to produce offensive-smelling isocyanides. The Reimer-Tiemann reaction is instead used for the ortho-formylation of phenols to produce hydroxybenzaldehydes like salicylaldehyde.
