New methods for the synthesis of bis(trifluoromethyl)sulfine (sulfoxide) (9) are reported.Pyrolysis, photolysis, and hydrolysis of the compound were investigated as well as the typical behaviour in reactions with the thiocarbonyl group (thiophosgene), with anthracene (Diels-Alder addition) and halogens.

The corresponding S-oxides 2-6 could be obtained by oxidation of 2,2,4,4-tetrakis(trifluoromethyl)-1,3-dithietane (1).Similar oxidation of 2,2,4,4-tetrakis(trifluoromethyl)thiirane (8) yields the episulfoxide 12, but not the episulfone 14.Pyrolysis of 2, 3, 5, and 6 have been investigated and bis(trifluoromethyl)sulfine (7) could be isolated as the first member of perfluoroalkylsulfines as well as the sulfonylfluoride 13 being the product of isomerization of bis(trifluoromethyl)sulfene (9). 7 could also be obtained by ring opening from 3 with bases and by oxidation of hexafluorothioacetone (11), respectively.Solvolytic ring opening in 5 and 6 yields the sulfones 16 and 17.
