Bis trifluoromethylthio mercury

Trifluoromethanesulfonic acid, also known as triflic acid [1493-13-6] is widely used ia organic syntheses and has been thoroughly reviewed (93,94). It was first prepared ia 1954 via the oxidation of bis(trifluoromethylthio)mercury with hydrogen peroxide [7722-84-1] (95). Several other routes of preparation have been disclosed (96—98). The acid exhibits excellent thermal and hydrolytic stabiUty, it is not readily oxidized or reduced, nor is it prone to fluoride anion generation.

Bistrifluoromethyl sulfide XLVII undergoes photolysis with ultraviolet light in a silica vessel, but not in Pyrex glass, yielding bistrifluoromethyl sulfide (XLIX) and sulfur.27 Possibly, irradiation leads to isomerization of XLVII and XLVIII, followed by S-S bond fission to give two CFjS- free radicals a view supported by the formation of bis(trifluoromethylthio)mercury (L) in the presence of mercury. The structures assigned for XLVII and XLIX find support from spectroscopic data.28...

When trifluoromethyl disulfide (CF3S)2 is in contact with mercury and the mixture is iriadiated by ultraviolet light, the two substances combine to form bis(trifluoromethylthio)mercury, (CF3S)2Hg (Brandt et al., 26), Bis(heptafluoropropylthio)mercury, (C3F7S)2Hg has also been produced (HI). The compound, (CF3S)2Hg, is also formed by the reaction of mercuric fluoride with carbon disulfide at about 250°. (CF3S)2Hg melts at 37-38° (220).
