A process for the manufacture of N-(substituted)-3-aminoacrylonitriles of the formula N--(R.sub.1 R.sub.2)--CH.dbd.CH--CN where R.sub.1 is alkyl, phenyl, phenyl substituted with alkyl and/or --NH.sub.2 groups, or --(CH.sub.2).sub.n --NH--CH.dbd.CH--CN and R.sub.2 is hydrogen or alkyl with the proviso that when R.sub.1 is --(CH.sub.2).sub.n --NH--CH.dbd.CH--CN R.sub.2 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.degree. C., and recovering the product at a temperature of not greater than 50.degree. C.
