A process for the manufacture of N-(substituted)-3-aminoacrylonitriles of the formula N-(R1R2)-CH=CH-CN where R1 is alkyl, phenyl, phenyl substituted with alkyl and/or -NH2 groups, or -(CH2)n-NH-CH=CH-CN and R2 is hydrogen or alkyl with the proviso that when R1 is -(CH2)n-NH-CH=CH-CN R2 is hydrogen, n being 1 to 8. The process comprises contacting cyanoacetylene with the appropriate amine in the presence of an inert atmosphere and at low temperatures, especially less than 40 DEG C., and recovering the product at a temperature of not greater than 50 DEG C.
