Zusammenfassung
A range of new fluorine-containing lithium salts generating interest as novel electrolytes for lithium batteries were synthesized from 2,2-difluoro-2-fluorosulfonylacetyl fluoride in three steps. The novel lithium salts are non-sensitive to moisture, thermally and electrochemically stable. Furthermore, it was demonstrated that the Ruppert-Prakash reagent is able to react with a number of cyclic imines under acidic condition to afford the corresponding α trifluoromethyl derivatives of nitrogen heterocycles. 5-7 Membered cyclic imines bearing various alkyl, aryl or heterocyclic group were successfully involved in this transformation. Novel trifluoromethylated analogues of nicotine, anabasine and homoanabasine alkaloids were synthesized.
