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