PURPOSE: To obtain new substd. heterocyclic triazinediones having considerably satisfactory herbicidal activity to weeds causing problem and satisfactory compatibility with important crops and useful as herbicides and insecticides.
CONSTITUTION: The substd. heterocyclic triazinediones are compds. of formula I (R1 is H, alkyl, alkenyl, alkynyl or cycloalkyl; R2 is alkyl, alkenyl, alkynyl or cycloalkyl; and Het, is an N-linked nitrogen-contg. heterocyclic ring which may contain other heteroatom), e.g. 1-(1-methyl-1-butyl)-4-(1-pyrazolyl)-1,3,5-(3H)- triazine-2,6-dione. The compds. of the formula I are obtd. by reacting 4- alkylthiotriazinediones of formula II (R3 is alkyl) with heterocyclic rings of formula III properly in the presence of a diluent.
