The reaction of perfluorinated indene, 3-methylindene, and 1-methylene- and 1-ethylideneindans with hydrogen peroxide in the hydrogen fluoride-antimony pentafluoride medium takes place at the multilple bond of the substrate and leads to the oxo derivatives of indan.The process probably takes place through the electrophilic addition of HO+.The C=C bond in perfluoro-3-methylindenone is not affected.In this compound and also in perfluoro-2-indanone and perfluoro-1-methyl-2-indanone the carbonyl group is involved in reaction with hydrogen peroxide in the HF-SbF5 system, and six-membered oxygen-containing heterocyclic compounds are formed.Keywords: Polyfluorinated indenes, alkylindeneindans, electrophilic hydroxyfluorination, polyfluorinated ketones, Bayer-Villiger reaction.

The reactions of polyfluoroindanes with Lewis acids were investigated.Indanes containing one (or two)dichloromethylene or carbonyl groups at positions 1,3 were obtained by the reaction of polyfluoroindanes with aluminum chloride and oleum. 1,1-Dichlorooctafluoro- and 1,1,3,3-tetrachlorohexafluoroindanes were synthesized from 1-chlorononafluoroindane and decafluoroindane and aluminum chloride.By the reaction of 1,1,3,3-tetrachlorohexafluoroindane with cesium fluoride or antimony trifluoride polyfluorochloroindanes with a smaller number of chlorine atoms than the initial compound were obtained.

A number of polyfluoro-1-methyleneindanes have been obtained by copyrolysis of 1,1-dichloropolyfluoroindanes with CF2=CF2, CHClF2, CHCl2F, CHCl3.A possibility is shown for the reaction of 1,1-dichloroctafluoroindan with CHClF2 to proceed by way of difluorocarbene insertion into the C - Cl bond of the benzylic position of this indan, with subsequent dechlorination of the insertion product.
