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 the preparation of pyrethroid type ester compounds

The present invention relates to a novel process for the preparation of insecticidally active esters of the general formula (I) STR1 wherein R1 and R2 are the same or diferent from each other and represent a hydrogen or a halogen atom; R3 represents STR2 (wherein R4 and R5 represent a chlorine or bromine atom or a methyl group when R4 is identical to R5, but R4 represents a chlorine or bromine atom or a methyl group and R5 represents a trifluoromethyl group when R4 is different from R5, and R6 represents a halogen atom or a difluoromethoxy group); and R8 represents a hydrogen or a cyano group. The characteristic of the present invention is a one-step procedure comprising directly condensing an organic acid, an aldehyde (and a water-soluble cyanide) in the presence of a phase transfer catalyst and a water-soluble inorganic base by the use of a sulphonyl compound as a condensing reagent.

Cyanophenoxybenzyl amines

The invention concerns novel compounds of the formula I STR1 wherein A, B, D and E are chosen from hydrogen, halogen, C1 to C6 alkyl, C1 to C6 haloalkyl and C1 to C6 alkoxy and Z is a tertiary or quaternary amino group. The compounds are useful intermediates for the preparation of pyrethroids. In further embodiments the invention provides processes for the preparation of the compounds of formula I and processes for the synthesis of pyrethroids utilizing the compounds of formula I.
