The syntheses of new terephthalic acids (8a-d) containing various polyfluoroalkyl groups (a ; CF3, b ; HCF2, c; H(CF2)3 and d ; H(CF2)5) are described in this paper. These compounds were obtained by aromatization (bromination and dehydro-bromination) of Diels-Alder adducts (2a-d and 3a-d) of polyfluoro- 2-alkynoic acids (1a-d) with 2-methyl-1, 3-butadiene, followed by oxidation with KMnO4.
