Question

mendius reaction with example

Answer 1

The reduction of cyanides to 1∘ amines by using ethanolic sodium is called as Mendius reaction.

A reaction in which an organic nitrile is reduced by nascent hydrogen (e.g. from sodium in ethanol) to a primary amine.

example:

$RCN+2H_{2} --- > RCH_{2} NH_{2} . RCN+2Hx_{2} --- > RCH_{2} NH_{2}$

Answer 2

Answer:

Mendius reaction:

• This is a sort of reaction that uses nascent hydrogen in the presence of sodium amalgam on ethanol to reduce the (-CN) cyano group in organic nitriles to obtain primary amines.
• Nascent hydrogen (e.g. from sodium in ethanol) reduces an organic nitrile to a primary amine:
• $RCN+2H_2 → RCH_2NH_2$
