“…Increased exibility leads to greater conductivity. 49,50 Therefore, a shorter skeleton and a more asymmetric structure of uorinated sulfonyl anions are more benecial to improving the conductivity. It should be pointed out that the conductivity calculated by Nernst-Einstein is generally lower than the experimental value, which may be due to the fact that we use the nonpolarized force eld.…”

“…The half-uorinated anions are more exible. 49,50 First, the system ran for 2 ns under the NPT ensemble (T = 350 K, P = 1 atm), and then continued to run for 10 ns under the NVT ensemble (T = 350 K) to achieve the equilibrium of the system. Finally, the data was collected in a 2 ns-simulation.…”

Chemoselective transformations of functionalized sulfonyl fluorides and chlorides are surveyed comprehensively. It is shown that sulfonyl fluorides provide an excellent selectivity control in their reactions. Thus, numerous conditions are tolerated by the SO2F group – from amide and ester formation to directed ortho‐lithiation and transition‐metal‐catalyzed cross‐couplings. Meanwhile, sulfur (VI) fluoride exchange (SuFEx) is also compatible with numerous functional groups, thus confirming its title of “another click reaction”. On the contrary, with a few exceptions, most transformations of functionalized sulfonyl chlorides typically occur at the SO2Cl moiety.

A set of mixed‐substituted potassium alkylcyano‐ and alkylcyanofluoroborates has been synthesized using easily accessible starting compounds and characterized by elemental analysis, NMR and vibrational spectroscopy, and mass spectrometry. In addition, single‐crystal structures of salts of the cyanoborate anions have been derived from X‐ray diffraction experiments. The 1‐ethyl‐3‐methylimidazolium room temperature ionic liquids ([EMIm]+‐RTILs) with the new borate anions have been synthesized and their physicochemical properties, that is, high thermal and electrochemical stability, low viscosity, and high conductivity, have been compared to the properties of related [EMIm]+‐RTILs. The influence of the different alkyl substituents at boron has been assessed. The exemplary study on the properties with the [EMIm]+‐ILs with the mixed water stable alkylcyanoborate anions points towards the potential of these fluorine‐free borate anions, in general.
