Fluorination of Sulfuryl Chloride—Sulfuryl Chlorofluoride

New hydrofluorocarbon (HFC) solvents for antimony pentafluoride

“…It should be pointed out that the ratio of isomers and the values of chemical shifts and coupling constants of the allylic fragment in cations 12a,b, 13a,b are very similar to ratio of isomers and NMR parameters observed for 10a,b (see Table 1, entry [13][14][15][16][19][20][21][22]. In both cases the large values of 4 J 1-3a (J = 115-137 Hz) in were observed in trans-isomers 12a and 12b and the absence of coupling constants 4 J 1-3a in 12b and 13b is in agreement with cisrelationship of substituents F 1 and F 2 .…”

“…Discovered in 1936, sulfuryl chlorofluoride (SO 2 ClF) [15] was employed as a solvent for generation of positively charged species by Olah and Gillespie [16][17][18][19][20]. Due to its high dielectric constant, low nucleophilicity, wide liquid range (bp 7.1 8C, mp À124.7 8C), and high chemical stability towards electrophilic reagents, SO 2 ClF became the solvent of choice for reactions involving strong oxidizers and Lewis acids, especially SbF 5 [3,6].…”

Inorganic Compounds Containing Sulfur and Fluorine

“…Sulfuryl Chiorofluoride, S02C1F, was first described by Davies and Dick in 1932 and was more carefully characterized by Booth and Herrmann in 1936 (5). The latter authors prepared it in good yields from sulfuryl chloride and antimony trifluoride in the presence of antimony pentachloride as a catalyst.…”

“…SgOsFipentachloride as a catalyst(5). Thionyl fluoride is a relatively stable compound which hydrolyzes only slowly in water, and does not attack glass below about 400 °C.…”

Chlorine monofluoride. Reactions with sulfur oxides

“…D. Pilipovich and K. O. Christe for helpful discussion Contribution from the Department of Chemistry, University of Florida, Gainesville, Florida 32601 Hydrogen Elimination in Dimethylamine-Borane By G. E. RYSCHKEWITSCH and J. W. WIGGINS Received August 18,1969 The elimination of hydrogen from dimethylamine-borane was studied at 100°b y observing the hydrogen isotope distribution in the products resulting from reactants with different hydrogen isotopes on nitrogen and/or boron. The results clearly eliminate the possibility of a unimolecular elimination and favor a bimolecular reaction.…”
