  • Patent number: 5187297
    Abstract: A process for the production of 3-aminocrotononitrile by dimerization of acetonitrile. In this process, the deprotonation step takes place with sodium amide as a strong base in the presence of liquid ammonia. 3-Aminocrotononitrile is used as an initial product for the production of pharmaceutical agents, pesticides or azo dyes.

  • Patent number: 5089651
    Abstract: A process for producing a 3-iminonitrile represented by the following general formula (I): ##STR1## wherein M represents an alkali metal, which comprises reacting acetonitrile with an alkali metal hydride in an amount of from 0.01 to 0.5 molar equivalent to acetonitrile; and a process for producing a 3-iminonitrile of the formula (II): ##STR2## which comprises mixing the compound represented by the foregoing general formula (II), which was obtained by the reaction between acetonitrile and the alkali metal hydride, with a protic solvent, are disclosed. These processes are useful for producing the desired 3-iminonitrile safely, inexpensively and in high yields.
