Fluorine-Containing Compounds Sulfur

When l,l,3,3-tetramethyl-2,l,3-thiadisilolane is used as sulfur reagent, another type of reaction takes place. Two molecules of the fluorine-containing compound become linked via a sulfur bridge with elimination of a fluorine atom from each.31 Thus, (4-fluorophenyl)phenyl-methanone reacts with l,l,3,3-tetramethyl-2,l, 3-thiadisilolane in TV. A -dimethylacetamide (with catalytic amounts of CsF, 12 h at 120 C, under N2) to give bis(4-bcnzoylphenyl) sulfide in 81 % yield.31...

The large number of fluorine-containing compounds of sulfur results from the ability of sulfur to form strong covalent bonds with itself or with fluorine, oxygen, carbon, chlorine, phosphorus, and nitrogen. It is also important that sulfur may have coordination numbers of 2, 3, 4, 5, and 6. Formulas of a few compounds which illustrate the versatility of sulfur are ... 

This review covers nearly the complete literature on fluorine-containing compounds of sulfur up through 1956. That is the last year for which a subject index for Chemical Abstracts or Chemisches Zentralblatt was available. Articles appearing through 1958 are also included when known to the reviewer. In the case of carbon compounds the review deals with the first member of an homologous series, for example... 

The earliest reference used in this review is dated 1888. In it and in the larger paper which followed in 1889 Thorpe and Rodgers (299) reported the preparation and properties of SPF3. With the exception of its length, a paper of this quality would be readily accepted for publication today. This was a good beginning for fluorine-containing compounds of sulfur.
