Preparation and Properties of Tetrakis(trifluoromethylthiazyl), (CF3SN)4

Bielefeldt, Dietmar,Haas, Alois

, p. 1257 - 1260 (2007/10/02)

Tetrakis(trifluoromethylthiazyl) was prepared from CF3SCl and (CH3)3SiN3.At -30 deg C it is stable for a few days.On standing it oligomerizes and after 7 days at 20 deg C the melting point is above 180 deg C.By addition of F2 to CF3SNCO at -78 deg C CF3S(F)N=C(O)F is formed in good yield.In the presence of HgF2 it decomposes at 25 deg C to (CF3SN)x. - 19F NMR, IR, UV, and mass spectra are given.
