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

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][ENTf2]) (water content similar to 0.13 M) 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.
