A novel and efficient method for the synthesis of polyfluoroarenesulfonyl bromides from polyfluoroarenethiols

“…This way is in agreement with the data of oxidative chlorination of polyfluoroarenethiols into polyfluoroarenesulfonyl chlorides [6] Scheme 1. and the conversion of sulfenyl chloride groups containing in polyfluorinated aliphatic polymers and alkane derivative to the sulfonyl chlorides by reaction in CFC-113 with Cl 2 in trifluoroacetic acid and water at about 100 8C or with aqueous sodium hypochlorite. Treatment of sulfenyl chloride derivatives of the polymers with HOFÁacetonitrile reagent afforded mixtures of the corresponding sulfonyl chloride and sulfonyl fluoride derivatives [11].…”

“…It is known that polyfluoroarenesulfonyl chlorides are used for preparation of the corresponding sulfonamides [6].…”

Organofluorine Sulfur-containing Compounds: V. Joint Pyrolysis with Chlorine or Bromine of Polyfluoroarenethioles, Polyfluorohetarenethioles, and Their Derivatives

“…ide. The main reaction product was the corresponding sulfochloride [23]. We demonstrated that at the joint pyrolysis of polyfluoroarenethiols with chlorine, its sources, or with bromine in a flow system at 300-650°C the thiol group was replaced by chlorine or bromine atoms furnishing the corresponding haloderivatives of the polyfluoroarenes (Tables 1 and 2, Scheme 1).…”

“…In the presence of thiol III sulfenyl chloride V can give disulfide IV [25] which treated with C1 2 also is converted into compound I. Therewith according to [23] it is presumable that disulfide IV with chlorine first transforms into sulfenyl chloride V. Thus the latter might be an intermediate on the route to compound I from thiol III and disulfide IV (Scheme 8). However the direct replacement of SH and C 6 F 5 SS groups with chlorine in compounds III and IV cannot be completely disregarded.…”

New fluorine-containing plasticized low lattice energy lithium salt for plastic batteries

“…3). Both routes (a) [13] and (b) [14] are adaptations of methods described previously. This newly characterized lithium salt is electrochemically and thermally stable and exhibits ionic conductivities comparable to those of LiTFSI (Fig.…”
