Direct Catalytic Conversion of Aldehydes to Nitriles

Nitriles are employed in many academic and industrial fields, especially organic synthesis. They are crucial precursors to synthesize aldehydes, amines, amides, carboxylic acids, and tetrazoles. There are many routes to synthesize nitriles from various species such as aldehydes, alcohols and amines. This review summarized the recently developed direct conversion of aldehydes to nitriles, focusing on the simple and efficient reaction.
