Insecticidal nitromethylene compounds
View Patent ↗A composition of matter is disclosed that comprises a compound of the formula: wherein R 1 is selected from the group consisting of unsubstituted and substituted biphenyl moieties, unsubstituted and substituted fluorenyl moieties, unsubstituted and substituted carbazolyl moieties, and unsubstituted and substituted pyridyl moieties; and R 2 is hydrogen or alkyl. The compositions are useful as insecticides, acaricides, and fungicides.
1. A composition comprising a compound of the formula:
wherein
R 1 is unsubstituted or substituted biphenyl; and
R 2 is hydrogen or alkyl.
2. The composition of claim 1 wherein R 1 is biphenyl, unsubstituted or monosubstituted by C 1 -C 4 alkyl, C 1 -C 6 alkoxy and R 2 is hydrogen or C 1 -C 6 alkyl or branched alkyl.
3. The composition of claim 2 wherein R 1 is unsubstituted biphenyl.
4. The composition of claim 2 wherein R 1 is monosubstituted biphenyl.
5. The composition of claim 1 wherein the compound is of the structure:
6. A pesticidal composition comprising:
(A) a pesticidally effective amount of a compound of the formula:
wherein:

7. The composition of claim 6 wherein:
R 1 is biphenyl, unsubstituted or monosubstituted by C 1 -C 4 alkyl, C 1 -C 6 alkoxy; and
R 2 is hydrogen or C 1 -C 6 alkyl or branched alkyl.
8. The composition of claim 7 wherein R 1 is unsubstituted biphenyl.
9. The composition of claim 7 wherein R 1 is monosubstituted biphenyl.
10. The composition of claim 6 wherein the compound is of the structure:
11. A method for controlling undesirable pests comprising applying to a locus to be protected a pesticidally effective amount of a compound of the formula:
wherein
R 1 is unsubstituted or substituted biphenyl; and
R 2 is hydrogen or alkyl.
12. The method of claim 11 wherein
R 1 is biphenyl, unsubstituted or monosubstituted by C 1 -C 4 alkyl, C 1 -C 6 alkoxy; and
R 2 is hydrogen or C 1 -C 6 alkyl or branched alkyl.
13. The method of claim 12 wherein R 1 is unsubstituted biphenyl.
14. The method of claim 12 wherein R 1 is monosubstituted biphenyl.
15. The method of claim 11 wherein the compound is of the structure:
16. The composition of claim 6 , wherein the carrier is selected from the group consisting of liquid carriers and solid carriers.
17. The composition of claim 6 , wherein the pesticidally effective amount is from about 0.1 to about 95 percent by weight.
