Synthesis and Structure of Aroylamidines and N-Arylbenzamidines Hydrochlorides. -Arylcarbonitriles (I) react with anhydrous ethanol in the presence of dry hydrogen chloride to the corresponding imidoesters which upon treatment with an alcoholic solution of ammonia yield aroylamidines (II) as salts. N-arylbenzamidines (V) are accessible by reacting benzonitrile (III) with arylamines (IV) in the presence of AlCl 3 . The structure of anilines not only affects the yield of the amidines, but can prevent their formation. -(KUVAEVA*, E. V.; FEDOROVA, E. V.; ZAITSEV, V. V.; YAKOVLEV, I. P.; ZAKHAROV, V.
