The present invention provides a class of substituted bicyclooctanes of formula ##STR1## wherein R is a C.sub.2-10 non-aromatic hydrocarbyl optionally substituted by cyano, halo, C.sub.1-4 alkoxy, C.sub.1-4 haloalkoxy or S(O).sub.m R.sup.3 ; R.sup.1 and r.sup.2 are independently hydrogen, halo, a C.sub.1-3 aliphatic group optionally substituted, S(O).sub.m,R.sup.4, or R.sup.1 and R.sup.2 and the carbon atoms to which they are attached form a C.sub.5-7 carbocyclic ring optionally substituted by halo, or a C.sub.1-3 aliphatic or alkoxy group;

Heterobicycloalkanes as pesticidal compounds

The present invention provides compounds of the formula (I): ##STR1## wherein R is a phenyl group, substituted fluorine atoms formulations containing them and their use in controlling pest infestation.

Pesticidal compounds

The present invention provides a class of novel substituted bicyclooctanes which have pesticidal activity, particularly against arthropod pests. Pesticidal formulations containing the compounds of the formula (I), their use in the control of pests and methods for their preparation are also disclosed.

Pesticidal bicyclo-octanes are of the formula ##STR1## where R is a substituted or unsubstituted aliphatic or aromatic group, R' and R.sup.3 are H or a substituted or unsubstituted aliphatic or aromatic group, R.sup.2 is a substituted or unsubstituted heterocyclic group containing at least one ring nitrogen and is preferably a 3- or 4- pyridyl group, Z is CH.sub.2 CH.sub.2, CH.sub.2 O--CH.sub.2 S or COCH.sub.2 or CH(OR.sup.5)CH.sub.2 where R.sup.5 is H, alkyl, acyl or carbamoyl at Y and Y' are O or S(O).sub.m where m is 0, 1 or 2. Various methods for their preparation are described.
