Schematic of the Ritter reaction. Reagents: nitrile, carbocation precursor, strong acid, water. Product: amide.

The Ritter reaction is an organic reaction used to convert a nitrile and a carbocation precursor (such as a substituted olefin or tertiary alcohol) to an amide using a strong acid and water. The mechanism begins with the formation of the carbocation from the reaction of the acid with the carbocation precursor. 1220019-95-3 manufacturer tert-Butyl 3-(methylamino)propanoate Price The nitrile then attacks the carbocation to form a nitrilium ion. Water hydrolysis and a series of proton transfer steps then yield the final amide product. [1][2]
