a
In the Stephen's reduction alkyl cyanide is reduced to aldehyde by $SnCl _2 / HCl$.
In the Stephen's reduction alkyl cyanide is reduced to aldehyde by $SnCl _2 / HCl$.
$R - C \equiv N +2 H \stackrel{ SnCl _2 / HCl }{\longrightarrow} \underset{\text { alidine }}{ RCH }=\underset{\text { hydrochloride }}{ NH \cdot HCl } \stackrel{ H _2 O }{\longrightarrow} \underset{\text { aldehyde }}{ RCHO }+ NH _4 Cl$
