Bis(trifluormethylsulfanyl)carben (CF3S)2C:; Generierung und Nachweis

Article abstract of DOI:10.1016/0022-1139(93)02896-M

Irradiation of bis(trifluoromethylsulfanyl)ketene (2) with UV light in an Ar matrix at 10 K produces CO, CS2 and C2F6, which have been identified by infrared spectroscopy and interpreted as the decomposition products of bis(trifluoromethylsulfanyl)carbene (1).Irradiation of 2 in n-hexane at 283 K provides the bis(trifluoromethylsulfanyl)methyl radical (3) as an unstable intermediate by ESR spectroscopy.If 2 is irradiated neat or in C6F6 solution, small yields of (CF3S)2C=C(SCF3)2 (5) are obtained.The formation of 3 from 1 is discussed.
