(EN) A method of producing fluorinated organic compounds such as organic sulphur pentafluorides. The method includes the steps of converting a compound such as R1-S-S-R2 into R1SF5 by reaction with an inert solvent of R1-S-S-R2 and elemental fluorine. R1 and R2 may be for example selected from aryl, heteroaryl, aliphatic or alycyclic groups.(FR) On décrit un procédé de production de composés organiques fluorés tels que des pentafluorures de soufre organiques, lequel consiste à convertir un composé tel que R1-S-S-R2 en un composé R1SF5, par mise en réaction dans un solvant inerte du composé R1-S-S-R2 et du fluor élémentaire. R1 et R2 peuvent être choisis, par exemple, dans des groupe aryle, hétéroaryle, aliphatiques ou alycycliques.
Preparation of (Pentafluorosulfanyl)benzenes by Direct Fluorination of Diaryldisulfides: Synthetic Approach and Mechanistic Aspects
using elemental fluorine afforded substituted (pentafluorosulfanyl)benzenes. This work thus represents the first study of the scope and limitation of direct fluorination for the synthesis of newSF5-containing building blocks. Fluorinations in batch and flow modes were compared. A comprehensive computational study was carried out employing density functional and wave function methods to elucidate the
