Abstract: The preparation of 5-X-3-(naphthal-1')phthalide and 6-X-3-(naphthal-1')phthalide (X = CI, Br) is described either by the condensation of 4-X-phthalic anhydride with 1-naphthylacetic acid, or via 5-nitro-3-(naphthal-1')phthalide and 6-nitro-3-(naphthal-1')phthalide. The phthalides thus prepared were subjected to the electrophilic substitution reactions on the naphthalene ring; the substitution was found to occur at position 4'.
