A variety of 6-substituted 3,5-diaryl-1,2,4-triazines were synthesized. These diaryltriazines, which incorporate a triazine nucleus substituted by two aryl moieties, comprise a new class of bleaching herbicides. The structure-activity relationships were proved by introducing a variety of substituents into the triazine and/or two aryl groups. The results indicated very specific structure requirements for herbicidal activity. Highest activity was seen with compounds that contain three substituents: a chlorine group at a meta position of an aryl moiety at the triazine 5-position, a fluorine group at the meta or para position of the other aryl moiety at the 3-position, and an ethylamino group at the 6-position of the triazine nucleus.
