    摘要: New 2-cyanobenzimidazoles of the formula (I) ##STR1## in which R.sup.1, R.sup.2 and A have the meaning given in the description, a preparation process, their use in agriculture, for example against fungi, insects etc., and new intermediates.Formula (I) provides a definition of the compounds; for example they are obtained from suitable 2-cyanobenzimidazoles which are unsubstituted in the 1-position with N,N-dimethylsulphamoyl halide. The 2-cyanobenzimidazoles which are unsubstituted in the 1-position are equally new and can be reacted from suitable phenylenediamines of the formula (IV) with methyl 2,2,2-trichloroacetimidate of the formula (V) to give the 2-trichloromethylbenzimidazoles of the formula (VI), which are equally new and from which the compounds of the formula (II) can subsequently be obtained with ammonia.
