Abstract: The preparation of 5-X-2-(4-Y-l-naphthyl)-l,3-indandiones and 5-X-2-(l-Y-2-naphthyl)-l,3-indandiones from the corresponding phthalides by
rearrangement with sodium methoxide in methanol as well as by condensation
of 4-X-phthalic anhydrides with 1-naphthylacetic acid and 2-naphthylacetic
acid, respectively, in the presence of triethylamine is described.
The starting 5(6)-X-3-(l-Y-2-naphthal)phthalides were obtained by chlorination,
bromination, and nitration of 5(6)-X-3-(2-naphthal)phthalides.
