Tetrafluoroterephthalyl alcohol, esters thereof and a process for their preparation
Tetrafluoroterephthalyl alcohol and its esters, useful in the synthesis of pesticidal compounds, are prepared by reducing a tetrafluoroterephthaloyl halide, especially the chloride, with suitably, sodium borohydride in diglyme, followed, as appropriate, by esterification. The alcohol and its esters...

| Zusammenfassung: | Tetrafluoroterephthalyl alcohol and its esters, useful in the synthesis of pesticidal compounds, are prepared by reducing a tetrafluoroterephthaloyl halide, especially the chloride, with suitably, sodium borohydride in diglyme, followed, as appropriate, by esterification. The alcohol and its esters can be further reduced by catalytic hydrogenation under mild conditions to yield tetrafluoro-p- xylene or the intermediate 4-methyl- 2,3,5,6-tetrafluorobenzyl alcohol. |
