Mono-cyanoethylation addition reactions of o-substituted or m-substituted anilines with acrylonitrile have been carried out in the presence of AlCl 3, resulting in N-β-cyanoethyl-o-substituted anilines, N-β-cyanoethyl-msubstituted anilines in high yield. Under the conditions of mole ratio of the reactants as substituted anilines; acrylonitrile: AlCl 3 = 1: 1. 10: (0. 05 - 0. 10),the temperature of 60-80°C for 6 - 10 h, the yields of monocyanoethyl substituted anilines were 87% -90 %,and capillary gas chromatographic determination method was ...
