Abstract:

Ionic liquids (IL) are a class of compounds that are used in several areas of technology. Imidazolium-bsed IL can be deprotonated at C2 position, due to the relative acidity of the C2-H hydrogen, leading therefire to the formation of N-Heterocyclic carbenes (NHC). NHC are highly reactive species that possess a very short half-life, being a hard task its experimental detection. We report herein the use of a negative charge tag for imidazolium NHC derivatives detection and characterization by ESI(-)- MS(/MS).
