Voltammetric studies in “wet” 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ionic liquid using electrodes with adhered microparticles

Abstract

The voltammetry of adhered microparticles provides a convenient method to access “water free” reversible potentials for water sensitive reduction of benzophenone and 1,4-benzoquinone in “wet” 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([Bmpyrd][NTf2]) (water content~0.13M) ionic liquid. The outcome that reflects reversible potentials relevant to “dry” conditions is rationalized in terms of generation of high localized concentrations that significantly exceed the water concentration near the electrode surface.
