Project dealt with purely synthetic chemistry, so, final results can be considered as satisfactory. Several students worked on the project. The work was presented on several conferences and in three papers (submitting next one is expected)."@en . "GAP207/11/0421" . . .

"We propose to synthesize four new fluorinated sulfur-containing reagents: (2-bromo-1,1,2,2-tetrafluoro-ethylsulfanyl)-benzene (PhSCF2CF2Br), trimethyl-(1,1,2,2-tetrafluoro-2-phenylsulfanyl-ethyl)-silane (PhSCF2CF2SiMe3), (2-bromo-1,1,2,2-tetrafluoro-ethanesulfonyl)-benzene (PhSO2CF2CF2Br) and (2-benzenesulfonyl-1,1,2,2-tetrafluoroethyl)-trimethylsilane (PhSO2CF2CF2SiMe3) in a few simple steps starting from 1,2-dibromotetrafluoroethane. New methodologies will be developed for nucleophilic and radical tetrafluoroethyl, tetrafluoroethylene, phenylsulfenyltetrafluoroethyl and phenylsulfonyltetrafluoroethyl group transfer with these reagents. It will allow access to novel fluorine-containing products, which are likely to serve as important intermediates in synthesis of bioactive compounds and new materials."@en .
