Density functional theory predicts a binuclear Fe2(μ-SF2)2(CO)8 octacarbonyl structure with two bridging SF2 groups and a long Fe⋯Fe distance of ∼3.5 A indicating a lack of a direct iron–iron bond. In addition, three Fe2(μ-SF2)(SF2)(CO)7 ster

Herein is described the development and use of a novel bis(dialkylamino)sulfur difluoride reagent to effect the stereoselective conversion of a benzylic alcohol into a benzylic fluoride. A new method for the synthesis of 1 H-pyrazolo[3,4- D]pyrimidin

CH3N=SF2=NCH3 (1) was obtained in 88% yield from the reaction of a bis(silylated) amine RN(SiMe3)2 with a sulfur tetrafluoride imide RN=SF4 (R = R = CH3). Single crystals suitable for X-ray crystallography were obtained by low-temperature crystalliza

In the reaction of TAS-fluoride, (Me2N)3S+Me3SiF2-, with carbonyl sulfur difluoride imides RC(O)NSF2 (R = F, CF3), C-N bond, cleavage is observed, and TAS+RC(O)F2- and NSF are the final products. From TASF and RC(O)NS(CF3)F, the salts TAS+RC(O)NS(CF3

Two new bis(imidazole)sulfur difluoride compositions, (imid)(2)SF(2) (2) and (4-Ph-imid)(2)SF(2) (4), have been prepared in high yields from the reactions involving the corresponding TMS precursors and excess SF(4) in anhydrous solvent. Mechanisms ar

SO3 adds across the CS double bond of H2C SF4 with formation of 2-tetrafluoro-4-dioxo-1,2,4-oxadithietane, which rearranges to fluorsulfonylmethylidene sulfur difluoride oxide, FSO2CH SF2 O in the presence of CsF. © John Wiley & Sons, Inc.

In this study, we have demonstrated the stand-off detection of sulfur hexafluoride by the Radar resonance multi-photon ionization process. In order to obtain a well defined spectral signature, the sulfur hexafluoride molecules are fi rst dissociated

The structures of sulfur tetrafluoride, SF4, dimethylaminosulfur trifluoride, Me2NSF3, and bis(dimethylamino)sulfur difluoride, (Me2N)2SF2 have been investigated using the PM3 semiempirical method. Full geometry optimizations do not agree with experi
