Formation and skeletal transformations of perfluoroindan-1-one and perfluoroindan-1,3-dione in the reaction of perfluoroindan with SiO 2/SbF5
Perfluoroindan-1-one (2) is obtained in the reaction of perfluoroindan (1) with SiO2/SbF5 at 70°C. Compound 1 heated with SiO2/SbF5 at 130°C and then treated with water, gives 3-hydroxy-perfluoro-3-methylphthalide (4). Ketone 2 is converted, under the action of SbF5 at 130°C, to perfluoro-2-ethylbenzoic acid (9) and disproportionates to compound 1 and perfluoroindan-1,3-dione (3); the latter is transformed to phthalide 4 under the reaction conditions.

Transformation of perfluorinated benzocycloalkenes and alkylbenzenes to their carbonyl derivatives under the action of CF3COOH/SbF5
Perfluorinated benzocycloalkenes (benzocyclobutene, indan, tetralin), alkylbenzocycloalkenes and alkylbenzenes react with CF3COOH/SbF5 at 20-50 °C giving the corresponding carbonyl derivatives.

Fluoroorganic sulphur-containing compounds. II. The synthesis of perfluoro-2,3-dihydrobenzothiophene and an investigation of some of its chemical properties
Perfluoro-2,3-dihydrobenzothiophene (I), along with some quantities of perfluoroindane, has been obtained by copyrolysis of a number of 4-substituted tetrafluorothiophenols with tetrafluoroethylene in the presence of iodine.The interaction of sulphide
