Abstract
Insect controlling compositions including an N-substituted (6-haloalkylpyridin-3-yl)alkyl sulfoximine compound exhibiting increased stability, along with methods for preparing same, are disclosed.
Claims20
A method, comprising:
- providing a composition including a first ratio between stereoisomers of a compound having the following formula (I):
- wherein
- X represents NO2, CN or COOR4;
- L represents a single bond or R1, S and L taken together represents a 4-, 5- or 6-membered ring;
- R1 represents (C1-C4) alkyl;
- R2 and R3 are distinct from each other and individually represent hydrogen, methyl, ethyl, fluoro, chloro or bromo;
- n is 1 when L represents a single bond or is 0 when R1, S and L taken together represents a 4-, 5- or 6-membered ring;
- Y represents (C1-C4) haloalkyl, F, Cl, Br, or I;
- and
- R4 represents (C1-C3) alkyl;
- and
- heating the composition in a manner effective to provide a second, distinct ratio between the stereoisomers.

A method, comprising:
- providing a composition including a stereoisomeric mixture of a compound having the following structure:
- wherein
- X represents NO2, CN or COOR4;
- R1 represents (C1-C4) alkyl;
- R2 and R3 are distinct from each other and individually represent hydrogen, methyl, ethyl, fluoro, chloro or bromo;
- Y represents (C1-C4) haloalkyl, F, Cl, Br, or I;
- R4 represents (C1-C3) alkyl;
- and
- the mixture is defined by a first pair of diastereomers and a second pair of diastereomers;
- and
- heating the composition to convert at least a portion of the second pair of diastereomers to the first pair of diastereomers.
8 more elements
A composition, comprising a stereoisomeric mixture of {1-[6-(trifluoromethyl)pyridin-3-yl]ethyl}(methyl)oxido-λ4-sulfanylidenecyanamide defined by a first pair of diastereomers and a second pair of diastereomers, wherein the first and second pairs of diastereomers are present at a ratio of at least about 3:1.
