Sulfinyl fluoride

When there is an a-hydrogen in the sulfide, the sulfuranes are unstable and cannot be isolated [775]. Sulfoxides [776] and sulfinyl fluorides [777] are oxidatively fluorinated with tluorine to give hexavalent sulfur compounds in yields up to 90%.

A solution of morpholinosulfur trifluoride (1 equiv) was added to a stirred cooled solution of the sulfonyl or sulfinyl chloride (1 equiv) in Et20 (or benzene, hexane, or chlorobenzene). The mixture was stirred at 20 C for 10 min and a precipitation of morpholinosulfur chloride difluoride occurred. The precipitate was filtered off under anhydrous conditions, and the filtrate was evaporated and fractionated to give the sulfonyl or sulfinyl fluoride.

The Friedel-Crafts sulfonylation of aromatics with alkane- and arenesulfonyl halides and anhydrides has been studied (Eq. 9) [23]. In the reaction of pentafluorobenzenesul-fonyl fluoride with pentafluorobenzene, decafluorodiphenyl sulfone is formed with deca-fluorodiphenyl [23c]. Certain phenylacetylenes react with SO2 and benzene in the presence of SbFs to form benzothiophene 5-oxide [24]. (Eq. 10). Sulfinyl fluoride reacts similarly with arenes under SbFs catalysis to give sulfoxides (Eq. 11) [25].
