Structural Dynamics of the First Alkylidenesulfur Difluoride Oxide, OFC-CH=SF2=O

The pentafluorosulfanylacetic acid, HOOC-CH2-SF5, is dehydrated to the ketene O=C=CH-SF5.Besides other more typical reactions this ketene isomerizes to the alkylidenesulfur tetrafluoride OFC-CH=SF4 which is hydrolyzed to the title compound OFC-CH=SF2=O.This first alkylidenesulfur difluoride oxide exists in three, possibly four different isomeric structures at low temperatures, as was determined by NMR techniques.This is a result of hindered rotation of the C=S and C-C bonds.
