PCT No. PCT/GB95/00954 Sec. 371 Date Oct. 21, 1996 Sec. 102(e) Date Oct. 21, 1996 PCT Filed Apr. 26, 1995 PCT Pub. No. WO95/29887 PCT Pub. Date Nov. 9, 1995A pesticidal compound of formula I: <IMAGE> (I) in which formula: either R1 is hydrogen and R2 represents a cyclopropyl group or R1 and R2 each represent an alkyl group, which alkyl groups may be the same or different; ArA represents an optionally substituted phenyl or naphthyl group; ArB represents a phenoxy, phenyl, benzyl or benzoyl-substituted phenyl group which is optionally further substituted; the configuration of the groups ArA-CR1R2 and -CH2ArB about the double bond being mutually trans. Preferably ArA 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 <IMAGE> and a compound comprising a moiety ArB- are reacted together forming a link -CH=C(F)CH2- between <IMAGE> and ArB in the compound of formula I.
