摘要

Fluorine-containing 4,6-diamino-s-triazines of the formula <IMAGE> wherein X is a chlorine atom, an alkoxy radical having 1 to 4 carbon atoms, an alkylthio radical having 1 to 4 carbon atoms or the azide radical, R1, R2 and R3 each independently is a hydrogen atom or an aliphatic radical, and R4 is a fluoroalkyl or fluorochloroalkyl radical, which possess herbicidal activity. Intermediates wherein X is chlorine and -NR1R2 is replaced by chlorine are also new.
