Benzimidazoles of the formula ##SPC1## Wherein R.sub.1 and R.sub.2 represent at least one alkyl group which may optionally be substituted and X is lower alkoxy or halo, R.sub.1 may also be dialkyl amino and R.sub.2 may be halo. The compounds are useful as intermediates for preparation of herbicides.
Benzimidazoles having 5-trifluoromethyl and 7-amino substituents are useful as herbicides. The 1-and 2-positions of the molecule also have at least one substituent; and, preferably both positions are substituted, such as with alkyl groups.
