Abstract: cf. CA 54, 21003a. Halogen and the nitro group were introduced into the title compds. (I) and (II), resp., in the 1-position of the naphthalene nucleus. Phthalide radical activated cationoid substitution on the naphthalene nucleus, modified by steric hindrance in the case of β-naphthalide. 2-[1-(X-substituted)-2-naphthyl]1,3-indandione (III) was synthesized where X was H, Cl, Br, or NO2. Thermal stability of III (X = I) and isomeric compds. was compared.
