A pesticidal compound of formula I: ##STR1## in which formula: either R.sup.1 is hydrogen and R.sup.2 represents a cyclopropyl group or R.sup.1 and R.sup.2 each represent an alkyl group, which alkyl groups may be the same or different; Ar.sub.A represents an optionally substituted phenyl or naphthyl group; Ar.sub.B represents a phenoxy, phenyl, benzyl or benzoyl-substituted phenyl group which is optionally further substituted; the configuration of the groups Ar.sub.A --CR.sup.1 R.sup.2 and --CH.sub.2 Ar.sub.B about the double bond being mutually trans. Preferably Ar.sub.A is a substituted phenyl group; more preferably being substituted at the 4-(para) position by halogen, alkoxy or haloalkyl. Further provided is a process for the preparation of a pesticidal compound of formula I in which a compound comprising a moiety ##STR2## and a compound comprising a moiety Ar.sub.B -- are reacted together forming a link --CH.dbd.C(F)CH.sub.2 -- between ##STR3## and Ar.sub.B in the compound of formula I.
公式I的杀虫化合物:##STR1## 其中公式中:R.sup.1为氢,R.sup.2代表环丙基或R.sup.1和R.sup.2各自代表烷基基团,该烷基基团可以相同也可以不同;Ar.sub.A代表可选择取代的苯基或萘基团;Ar.sub.B代表苯氧基、苯基、苄基或苯基取代的苯基团,该苯基团可选择进一步取代;关于双键的Ar.sub.A--CR.sup.1 R.sup.2和--CH.sub.2 Ar.sub.B基团的构型相互为反式。最好Ar.sub.A是取代的苯基团;更好地是在4-(对位)位置被卤素、烷氧基或卤代烷基取代。还提供了一种制备公式I中的杀虫化合物的方法,其中包含一种含有基团##STR2##和一种含有基团Ar.sub.B--的化合物反应,形成##STR3##和Ar.sub.B之间的连接--CH.dbd.C(F)CH.sub.2--在公式I的化合物中。
