✦ Synopsis

The syntheses of new terephthalic acids (8a-d) containing various polyfluoroalkyl groups (a ; CF3, b ; HCF2, c ; H(CF2)3, and 4 ; H(CF2)5) are described in this paper. These compounds were obtained by aromatization (bromination and dehydrobromination) of Diels-Alder adducts (2a_d and 3a-d) of polyfluoro-2-alkynoic acids (la_a) with 2-methyl-1,3-butadlene, followed by oxidation with KMn04.
