| titleOfInvention | Process for the preparation of insecticidally active diphenyl ether compounds |
| abstract | The invention provides a process for the preparation of insecticidally active compounds of formula (I) : <CHEM> where X represents hydrogen or fluoro, W represents hydrogen or halo, Z represents halo, alkyl, alkoxy, haloalkyl or haloalkoxy, and Q is a group of formula -(CF2)nR<1> where R<1> is hydrogen, fluoro or chloro and n is one or two, which comprises the step of Wittig reaction between a Wittig reagent of formula A- @(R<2>)3 Hal<-> or formula A-P(O)(OR<2>)2, where R<2> represents alkyl or aryl and A represents the group of formula <CHEM> followed by the step of reduction of the resulting diene to give the compounds of formula (I). The invention also provides novel intermediates for use in the process, and further processes for their preparation. |
