3-Amino-2-cyanoacrylonitrile derivatives of the formula <IMAGE> where R is substituted C1-C10-alkyl, substituted or unsubstituted styryl, substituted or unsubstituted phenyl or aromatic heterocyclyl, are prepared by treating a nitrile in an inert organic diluent at from 0 DEG to +30 DEG C. with a substituted or unsubstituted C1-C6-alkanol in the presence of a hydrogen halide and reacting the resulting iminoester hydrohalide directly or after isolation with malodinitrile in an inert organic diluent at from 20 DEG to 100 DEG C. in the presence of a base. |
