Chemical Properties of Amines

A primary ami...

Question

A primary amine, $R N H_{2}$ can be reacted with $C H_{3} - X$ to get secondary amine, $R - N H C H_{3}$ but the only disadvantage is that $3^{\circ}$ amine and quaternary ammonium salts are also obtained as side products. Can you suggest a method where $R N H_{2}$ forms only $2^{\circ}$ amine?

Solution

Carbylamine reaction can be used to produce a secondary amine only from primary amine. This reaction is shown by $1^{\circ}$ amine only which results in the replacement of two hydrogen atoms attached to the nitrogen atom of $N H_{2}$ group by one carbon atom. On catalytic reduction, the isocyanide will give a secondary amine with one methyl group.

$R N H_{2} K O H + C H C l_{3} - -------- \to R N C H_{2} / P d - --- \to R N H C H_{3}$
