Photochemical Behaviour of Bis(trifluoromethylthiyl)trithiocarbonate in Solution

Bis(trifluoromethylthiyl))trithiocarbonate showes electronic transitions at 496 nm (n?*), 299 nm (??*) and 259 (n?*).Photolysis with 254 and 300 nm light at 200 and 309 K in pentane, and at 371 K in heptane yields a mixture of CS2 and perfluorinated compounds such as F3CSCF3, F3CSSCF3, (F3CS)3C-C(SCF3)3, (F3CS)2C=C(SCF3)2, (F3CS)3CH and F3CS-substituted solvent.The concentration of these newly formed products versus time of irradiation has been monitored.The primary photochemical process is the intramolecular decomposition into CS2 and F3CS and F3C radicals which dimerize in a solvent cage.The formation of (F3CS)3C-C(SCF3)3 is interpreted in terms of a competition between this combination process and trapping of trifluoromethyl radicals by (F3CS)2CS, forming (F3CS)3C, which subsequently dimerizes.On irradiation at 496 nm (n?*) no photochemical process has been observed. - Key words: Bis(trifluoromethylthiyl)trithiocarbonate, Electronic Spectra, Photochemical Behaviour, Tris(trifluoromethylthiyl)methyl Radical
