Nitrile reduction


Nitrile reduction

In nitrile reduction a nitrile is reduced to either an amine or an aldehyde with a suitable chemical reagent [1].

Nitrile reduction

Reagents for the conversion to amines are lithium aluminium hydride, Raney nickel / hydrogen / [2] [3] [4] or diborane [5] This organic reaction is one of several nitrogen-hydrogen bond forming reactions.


Nitriles can also be reduced to aldehydes. One method is called the Stephen aldehyde synthesis (Tin(II) chloride, hydrochloric acid and hydrolysis of the iminum salt). Aldehydes also form by reduction with hydrogen with in-situ hydrolysis of the imine. Reagents are Raney nickel [6], lithium aluminium hydride and sodium borohydride.
