Description
PESTICIDAL COMPOUNDS
The present invention relates to novel chemical compounds having pesticidal activity, to methods for their preparation, to compositions containing them and to their use in the control of pests. More particularly the invention relates to a class of l,3,4-tri-substituted-2,6,7-trioxabicyclo[2,2,2]octanes.
The use of certain 2,6,7-trioxabicyclo[2,2,2]octanes as pesticides is disclosed in European Patent Application No. 152 229; it has now been discovered that derivatives of these compounds having substituents at the 3-position have interesting pesticidal activity.
Accordingly the present invention provides a compound of the formula (I):
wherein R is C2_ig alkyl, alkenyl or alkynyl, each optionally substituted by or methyl substituted by cyano, cycloalkyl, halo, alkoxy or a group
S(O)m R^ where R^ is alkyl and m is Ο, 1 or 2 , or R is Cj.^g cycloalkyl, cycloalkenyl or phenyl, each optionally substituted by Cj^ alkoxy, , alkyl,alkynyl, halo, cyano or a group S(0)m R^ as defined hereinbefore; R* is halo, alkyl, C2_j adenyl or alkynyl each optionally substituted by halo, cyano,alkoxy, alkyl carbalkoxy containing up to 6 carbon atoms, a group S(0)m R4 as defined hereinbefore or alkynyl substituted by tri-C. . alkylsilyl, or
R is cyano, spiro-cyclopropyl, gem dimethyl, gem dicyano, gem diethynyl, oxo or methylene optionally substituted by cyano or alkyl optionally substituted by fluorine, or R^ and R and the carbon atoms to which they are attached form a ? carbocyclic ring optionally substituted by halo, Cj.j alkyl or alkoxy or C2.} alkenyl, R^ is phenyl, ^g cycloalkyl or cycloalkenyl each optionally substituted and R5 is hydrogen, alkyl, C2_j alkenyl or alkynyl each optionally substituted by cyano, Cj alkylthio, alkoxy or halo, or R^ is cyano or halo.
Suitably R is propyl, butyl, pentyl, alkenyl or alkynyl, ? cycloalkyl or phenyl each optionally substitued by one to three fluoro, chloro or bromo. Most

BIOLOGICAL ACTIVITY
The compound number refers to the numbers allocated to the compounds in the table spanning pages 41 to 44.
A. Lethal activity against House flies
The activity of compounds of the invention against unanaesthatised female Musca domestica (WRL strain), was demonstrated by the topical application to the test insect of a solution of the compound under test in butanone.
The activity of the test compound was also assessed when applied topically in conjunction with a synergist [6yg piperonyl butoxide (PB) per insect]. Mortality was assessed after 24 and 48 hrs.
The following compounds were active at less than 30 pg/fly:
1,11,12,15,16,19,20,22,37,38,40,41,42,44,45,46,47,48,49,50,17,32,33,34.
The following compounds were active at less than 1 yg/fly:
6,7,8,9,10,13,14,18,21,23,24,25,26,27,29,30.
B. Lethal Activity Against Blattella qermanicaThe activity of oompounds of the invention against unaesthetised male Blatella germanica (WRL strain) was demonstrated by the topical application to the test insect of a solution of the compound under test in butanone.
The activity of the test compound was assessed when applied topically in 20 conjunction with a synergist [lOyg piperonyl butoxide (PB) per insect]. Mortality was assessed after 24 and 48 hours.
The following compounds were active at less than 50 yg/insect:
The collowing compounds were active at less than 5yg/insect:

-51P5/6/15
6,7,9,9,29,30.
C. Lethal Activity Against Sitophjlus granarius
The activity of the compounds of the invention against S.granarius adults was demonstrated by addition of the compound in acetone solution to grain, to which the insects were later infested. Mortality was assessed after 6 days
The following compounds gave activity at less than 200 ppm solution of acetone:
16,18,19,20,22,23,216,27,37,41,42,43,44,32,33,34.
The following compounds gave activity at less than 50 ppm solution of acetone:
6,14,15,21,25,29.
D. Lethal activity against Culex quinquefasciatus
The activity of the compounds of the invention against female Culex adults was demonstrated by direct spraying of 0.5 ml of compound in OPD/Methylene chloride. Mortality was assessed after 24 hours.
The following compounds were active at less than 1.0%:
6,12,14,15,18,19,21,22,23,24,25,26,27,37,39,41,43,44,48,50,33.
The following compound was active at less than 0.1%:
