1-cycloalkenyltetrazolinone derivatives of the following herbicidal formula ##STR1## R.sup.1 is cycloalkenyl which may optionally be substituted by halogen C.sub.1-4 alkyl, or bicycloalkenyl which may optionally be substituted by halogen or C.sub.1-4 alkyl, and R.sup.2 and R.sup.3 each independently is alkyl, cycloalkyl, phenyl (optionally substituted by a member selected from the group consisting of nitro, cyano, halogen, alkyl, haloalkyl, alkoxy, haloalkoxy and alkylthio), alkenyl and alkynyl, or R.sup.2 and R.sup.3 together with the N-atom to which they are bonded form, a 5- or 6-membered heterocyclic ring which may optionally contain a further hetero atom, said heterocyclic ring optionally being benzo-condensed, or a C-.sub.1-4 alkyl, and intermediates therefore of the formula ##STR2##
以下是具有以下除草剂结构的1-环烯基四唑啉酮衍生物的公式:##STR1##其中,R.sup.1是环烯基,可以选择性地被卤素C.sub.1-4烷基或者可以选择性地被卤素或C.sub.1-4烷基取代的双环烯基所取代,而R.sup.2和R.sup.3各自独立地是烷基、环烷基、苯基(可以选择性地被从亚硝基、氰基、卤素、烷基、卤代烷基、烷氧基、卤代烷氧基和烷硫基中选择的一种成员取代),烯基和炔基,或者R.sup.2和R.sup.3与它们连接的N原子一起形成一个5-或6-成员杂环,该杂环可以选择性地包含进一步的杂原子,所述杂环可以选择性地被苯并,或者是C-.sub.1-4烷基,其中间体的公式为:##STR2##
