\(R-\ddot{N}_{H_{2}}+C H C I_{3} \frac{C_{2} H_{5} O H}{K O H} R-_{N}^{+} \equiv \bar{c}^{:}\)
\(1^{\circ}\; amine     \quad   \quad   \quad \quad \quad \;Alkyl \;isocyanide\)

The mechanism of this reaction included rearrangement of nitrene in which migration of alkyl group from carbon to nitrogen takes place.
