AGRICULTURAL CHEMICALS

The present invention relates to derivatives of compounds which are known to be of use in the field of agriculture. These derivatives are differentiated from the parent active compound by virtue of being redox derivatives of the active compound. This means that one or more of the functional groups in the active compound has been converted to another group in one or more changes one or more of which may be considered to represent a change of oxidation state relative to the groups in the original compound. We refer to these compounds generally as redox derivatives. The compounds are of use as insecticides, herbicides and insect repellents.

PROCESS FOR PRPARING GAMMA-CYHALOTHRIN

A process for the preparation of gamma-cyhalothrin comprising steps of a) chlorinating 1R cis-Z 3-(2-chloro-3,3,3-trifluoro-l-propenyl)-2,2-dimethyl cyclopropanecarboxylic acid to give 1R cis-Z 3-(2-chloro-3,3,3-trifluoro-l-propenyl)-2,2-dimethyl cyclopropanecarboxylic acid chloride and b) esterifying 1R cis-Z 3-(2-chloro-3,3,3-trifluoro-l-propenyl)-2,2-dimethyl cyclopropanecarboxylic acid chloride with the (S)-cyanohydrin of 3-phenoxy benzaldehyde (III).
