Observation of aliphatic C-H···X hydrogen bonds in imidazolium ionic liquids

Observation of aliphatic C-H···X hydrogen bonds in imidazolium ionic liquids

Measurement of H/D isotope effects on the (19)F resonances of sequentially deuterated 1-n-butyl-3-methylimidazolium hexafluorophosphate and tetrafluoroborate isotopologues reveals the formation of aliphatic C-H···X hydrogen bonds between the fluorinated anions and protons along the N-alkyl sidechain...

Zusammenfassung:Measurement of H/D isotope effects on the (19)F resonances of sequentially deuterated 1-n-butyl-3-methylimidazolium hexafluorophosphate and tetrafluoroborate isotopologues reveals the formation of aliphatic C-H···X hydrogen bonds between the fluorinated anions and protons along the N-alkyl sidechains of the cations.
