Reaction of 1,2,5-trifluorbenzene with sodiummethylmercaptide yields difluorothioanisol. 60 and 220 MHz proton- and 56 MHz fluorine-resonance-spectroscopy established the structure of 2,5-difluorothioanisol. Methods and results of ABCXY-spectralanalysis are discussed together with the NMR parameters obtained.

Lithium bis(fluorosulfonyl) imide (LiFSI) is an interesting electrolyte for lithium ion batteries and valeronitrile is a good solvent for LiFSI as it forms complexes with the Li+-ions. In the present work, this complexation was studied by optical spectroscopy (Raman and IR), as well as by nuclear magnetic resonance (NMR) spectroscopy. Based on these spectrocopic information a chemical model for the complexation was developed and the equilibrium constants for the formation of the different species that were considered are reported.
