Selective Formation and Characterization of a RhIII Difluorido λ4‐Trifluorosulfanyl Complex

“…Comparable chemical shifts were found for other compounds bearing SF 3 units. [5b], [5d], [5e], , , The presence of three distinct resonances for the fluorine atoms of the λ 4 ‐trifluorosulfanyl unit additionally indicates the presence of a stereoactive electron pair at the sulfur atom …”

First Detection of a Selenenyl Fluoride ArSeF by NMR Spectroscopy: The Nature of Ar2Se2/XeF2 and ArSeSiMe3/XeF2 Reagents

“…In the reaction of ArSeSiMe 3 and XeF 2 the intermediate formation of the selenenyl fluoride is likely followed by reaction with ArSeSiMe 3 to give Ar 2 Se 2 (Scheme ) 37. There is an analogy with the sulfur series 38–40. Marginally stable CF 3 SF dimerizes to CF 3 SSF 2 CF 3 .…”

“…[37] There is an analogy with the sulfur series. [38][39][40] Marginally stable CF 3 SÀF dimerizes to CF 3 SSF 2 CF 3 . This reacts further to give CF 3 SF 3 and CF 3 SSCF 3 with an excess of CF 3 SÀF.…”

Synthesis and properties of sulfur cyanide trifluoride, SF3CN, sulfur dicyanide difluoride, SF2(CN)2, and sulfinyl cyanide fluoride, FS(O)CN

“…3), and the observed vibrational wavenumbers are summarized in table 3. Since the FS(0)CN molecule has C , symmetry, the irreducible representation of the normal modes is r,,,, = 9a'(IR, Rap) (8) Of these 9 expected fundamcntals, 8 are unequivocally identified and assigned in coniparison with spectra of similar molecules. For all bonds (CN, SO, SF, and CS), the characteristic vibrations are observed.…”
