Summary of the invention
Novel tetrazolinone derivatives of the formula (I) and intermediates of the formula (II) for production thereof represented by the following formulas
wherein
X represents C1-4 alkyl,
n represents 1, 2, 3 or 4,
R1 and R2 each independently represents C1-6 alkyl, C2-4 alkenyl, C2-6 alkynyl C3-8 cycloalkyl, aryl which may optionally be substituted (wherein the substituent is at least one radical selected from the group consisting of halogen, C1-4 alkyl, C1-2 haloalkyl, C1-2 haloalkoxy, C1-2 haloalkylthio, acyl, nitro and cyano) or aralkyl which may optionally be substituted by halogen, or
R1 and R2 may form, together with the N-atom to which they are bonded, a cyclic ring which may optionally be substituted.
The above tetrazolinone derivatives of formula (I) have an excellent activity as the effective component in herbicides.
