Bis(trifluormethylsulfanyl)carben (CF3S)2C:; Generierung und Nachweis
Dorra, Michael,Haas, Alois
, p. 91 - 94 (1994)
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.

supporting information, p. 5528 - 5533 (2019/11/14)
A novel Ph2P(O)Cl-mediated direct fluoroalkanesulfinylation of electron-rich (het)arenes using fluoroalkyl heteroaryl sulfones as the RfSO source (Rf=C4F9, CF2Cl, CF2Br, and CF2COOEt) was developed. This is the first example where 2-HetSO2Rf performs as the RfSO synthon in organic synthesis via both C(Het)?S and S=O bond cleavage. (Figure presented.).

Photolysis of matrix-isolated CF3C(O)SH and CF3C(O)SCl
Ulic,Gobbato,Della Vedova
, p. 171 - 175 (2007/10/03)
Perfluoroacetylthiol, CF3C(O)SH, and perfluoroacetylsulphenyl chloride, CF3C(O)SCl, were irradiated in an inert gas matrix to produce CF3SH and CO, and CF3SCl, CF3Cl, CO and SCO, respectively. The compounds are identified by evaluating the apparition of new bands in the FTIR spectrum of the matrix-isolated substance. The results are compared with related studies of similar compounds taking into account both the irradiation and the stability of the formed products.

Oxidative halogenation of CF3SN(SiMe3)2 with F2 or Cl2 leads to CF3S(X)=NX (X=F, Cl) (2a, b).During the chlorination process CF3S(Cl)=NSiMe3 (3a) was isolated and characterized as an intermediate.It reacts with CF3SCl to give CF3S(Cl)=NSCF3 (3b) which was also obtained from (CF3S)2NH and Cl2 at -60 deg C.Similarly, CF3S(F)=NSCF3 (3c) was synthesized from (CF3S)2NH and F2 or from CF3SF3 and CF3SNH2. 3a-c decompose already at temperatures 5a, b).Analoguosly, CF3SN=S=NSCF3 (4b) reacts with cyclopentadiene to give 5c.Ringopening takes place during the reaction of + Cl- (6) with Hg(SCF3)2 with formation of CF3SSN=S=NSSCF3 (7) which was also obtained from (CF3SS)2NH and (ClSN)3 in the presence of pyridine.Physical and spectroscopic data of the compounds are reported.
