Alcohol to nitrile
Reducing agents for the non-catalytic conversion to amines include lithium aluminium hydride, lithium borohydride, diborane, or elemental sodium in alcohol solvents. Nitriles can also be converted to aldehydes by reduction and hydrolysis. The Stephen aldehyde synthesis uses Tin(II) chloride and hydrochloric acid to yield a… WebHow do you convert nitriles to alcohol? You can do an acid-catalyzed hydrolysis with heat, followed by a very strong hydride donor. Nitriles are quite hard to hydrolyze, and you’ll …

WebIn a manner very similar to alkynes, nitriles show a prominent band around 2250 cm-1 caused by the CN triple bond. This band has a sharp, pointed shape just like the alkyne C-C triple bond, but because the CN triple bond is more polar, this band is stronger than in alkynes.
