Paragraph 0028; 0029, (2021/02/19)
The present invention aims to provide a method by which fluorine-containing sulfide compounds, particularly sulfide compounds that contain hydrogen and fluorine, can be produced in a simple, low-cost and industrial manner. Provided is a method of producing a fluorine-containing sulfide compound represented by the following formula (2): [in-line-formulae](F)n-A3-S-A4-(F)m??(2)[/in-line-formulae] (wherein A3 and A4 are independently an optionally substituted hydrocarbyl group with a carbon number of 1 to 3; n and m represent the numbers of fluorine atoms binding to A3 and A4, with n+m=1 to 13 being satisfied), comprising reacting a chlorine-containing sulfide compound represented by the following formula (1): [in-line-formulae](Cl)n-A1-S-A2-(Cl)m??(1)[/in-line-formulae] (wherein A1 and A2 are independently an optionally substituted hydrocarbyl group with a carbon number of 1 to 3; n and m represent the numbers of chlorine atoms binding to A1 and A2, with n+m=1 to 13 being satisfied) and a fluorinating agent.
Selective aliphatic fluorination by halogen exchange in mild conditions
Saint-Jalmes, Laurent
, p. 85 - 90 (2007/10/03)
HF-Base media, in particular (HF)10-pyridine or (HF) 3-triethylamine, allow aliphatic chlorine-fluorine exchanges on acid-sensitive molecules. Depending on the nature (pyridine or triethylamine), stoichiometry of the base and temperature, selective mono-, di-, or tri-chlorine-fluorine exchanges on trichloromethyl groups alpha to sulfur, oxygen and carbon atoms can be obtained.
A new synthesis of trifluoromethanethiolates - Characterization and properties of tetramethylammonium, cesium and di(benzo-15-crown-5)cesium trifluoromethanethiolates

, p. 101 - 107 (2007/10/03)
[NMe4]SCF3, CsSCF3 and [(B-15-C-5)2Cs]SCF3 (B-15-C-5: benzo-15-crown-5) are formed from reactions of the corresponding fluorides, trimethyl(trifluoromethyl)silane, Me3SiCF3, and elemental sulfur in glyme or THF. All compounds are colorless to pale ochre solids decomposing significantly above ambient temperature. Excellent agreement between experimental and theoretical vibrational frequencies, calculated at the B3PW91 level of theory, impressively confirms the salt-like nature of [NMe4]SCF3. The properties of the title compounds as nucleophilic SCF3 transfer reagents were checked with a variety of organic, organometallic and inorganic compounds.
A new simple access to trifluoromethyl thioethers or selenoethers from trifluoromethyl trimethylsilane and disulfides or diselenides
Billard, Thierry,Langlois, Bernard R.
, p. 6865 - 6868 (2007/10/03)
Trifluoromethyl thioethers (or selenoethers) are easily obtained in one pot at 0°C from disulfides (or diselenides), commercial trifluoromethyl trimethyl silane and TBAF.

-
, (2008/06/13)
The present invention relates to a process for the preparation of perhaloalkylthioethers by bringing a perhaloalkyl halide, preferably a bromide or an iodide, into contact with a disulphide in the presence of zinc and of sulphur dioxide or of a dithionite or of a hydroxymethanesulphinate or of a formate anion and sulphur dioxide.
REACTIONS OF BROMOTRIFLUOROMETHANE AND RELATED HALIDES PART VII CONDENSATIONS WITH THIOCYANATES AND ISOCYANATES IN THE PRESENCE OF ZINC
Tordeux, M.,Francese, C.,Wakselman, C.
, p. 27 - 34 (2007/10/02)
Reaction of zinc and bromotriflouromethane, or perfluroalkyliodides, with thiocyanates and isocyanates gives respectively trifluromethylsulfides and substituted trifluroacetamides, as well as their long chain analogs.
Reactions of CF3XXCF3 (X = S, Se) with the Esters of Phosphoric Acid
Haas, Alois,Lopusinski, Andrzej
, p. 3176 - 3178 (2007/10/02)
Reactions of CF3SSCF3 with (CH3O)2PR give CF3SP(O)(OCH3)R .Similarly CF3SeSeCF3 reacts with (CH3O)3P to form the corresponding CF3SeP(O)(OCH3)2 (2a).If CF3SSCF3 is combined with (C2H5O)2P(O)H good yields of CF3SP(O)(OC2H5)2 (1b) are obtained.On heating 1b decomposes to FP(O)(OC2H5)2.IR and 19F NMR data of the newly prepared substances are presented.
