Abstract

"PROCESSO PARA A PREPARAçãO DE áLCOOL 4-METIL-2,3,5,6-TETRA-FLUOROBENZìLICO, E, COMPOSTO". Um processo para a preparação do álcool 4-metil-2,3,5,6-tetrafluorobenzílico que compreende hidrogenar a 4-metil-2,3,5,6-tetrafluorobenzonitrila a 4-metil-2,3,5,6-tetrafluorobenzilamina e converter a 4-metil2,3,5,6-tetrafluorobenzilamina ao álcool 4-metil-2,3,5,6-tetrafluoro-benzílico. O processo, opcionalmente, também compreende a outra etapa de reagir o álcool 4-Metil-2,3,5,6-tetrafluorobenzílico com o cloreto de cis-Z-3-(2-cloro-1,1,1-trifluoro-2-propenil)-2,2-dimetilciclopropanocar bonila à forma teflutrina. A 4-metil-2,3,5,6-tetrafluorobenzilamina e seus sais também são reivindicados.
