Abstract
The invention concerns a process for preparing 2-substituted-3,4,5,6-tetrafluorobenzyl alcohols by reaction of pentafluorobenzyl alcohol with a Grignard reagent under specified conditions. The products some of which are novel are useful as intermediates for insecticidal esters e.g. those with pyrethroid acids. A typical ester is 2-methyl-3,4,5,6-tetrafluorobenzyl 3-(2-chloro-3,3,3-trifluoroprop-1-en-1-yl)-2,2-dimethylcyclopropane carboxylate.
