; tetrafluorinated cyclohexadiene; tetrafluorinatedcyclohexane; Introduction
Fluorine-containing organic compounds have attracted much attention in various areas, such as the medicinal, agrochemical, and materials science fields [1][2][3], due to the unique characteristics of the fluorine atom [4][5][6]. It is
compound 4a in hand, the successive hydrogenation in the presence of 20 mol % of Pd/C in methanol was performed for 1 d and generated the corresponding tetrafluorinatedcyclohexane-1,4-diol 3a in quantitative yield. Compound 3a could be converted to the cyclohexadiene 1a in 82% isolated yield under the
