A 1-aryl-pyrazole of the formula ##STR1## in which R represents cyano or nitro, Ar represents in each case optionally substituted phenyl or pyridyl, X represents an azido group, or represents the radical ##STR2## and R.sup.1, R.sup.2 and R.sup.3 each independently represents alkyl, alkenyl, alkinyl, halogenoalkyl, alkoxy, alkoxyalkyl, cycloalkyl or cycloalkyloxy, or represents in each case optionally substituted aryl, aryloxy, aralkyl or aralkyloxy, but wherein, in the case where R represents cyano and X simultaneously represents an azido group, Ar does not represent unsubstituted phenyl and does not represent 5-nitro-2-pyridyl. The compounds exhibit herbicidal and plant growth-regulating activity.
公式为##STR1##的1-芳基吡唑,其中R代表氰基或硝基,Ar分别代表可选择取代的苯基或吡啶基,X代表一个偶氮基团,或者代表基团##STR2##,R.sup.1,R.sup.2和R.sup.3分别独立地代表烷基,烯基,炔基,卤代烷基,烷氧基,烷氧基烷基,环烷基或环烷氧基,或者分别代表可选择取代的芳基,芳氧基,芳基烷基或芳基烷氧基,但在R代表氰基且X同时代表偶氮基团的情况下,Ar不代表未取代的苯基,也不代表5-硝基-2-吡啶基。这些化合物表现出除草和植物生长调节活性。
