Webb6 sep. 2024 · The catalysts with protic cations showed enhanced activity compared to those without protic cations, as indicated by the positive shifts in the half-wave potential … WebbProtic Ionic Liquids. Recently, we have used OHD-OKE experiments and atomistic simulations to study protic ionic liquids, which are ionic liquids with an acidic proton on the cation. Protic ionic liquids have advantageous properties that make them ideal for applications in many fields including electrochemistry, biochemistry, and synthesis.
WebbPolar protic solvents solvate cations only. Polar aprotic solvents are capable of intermolecular hydrogen bonding. In polar protic solvents, nucleophilicity increases down a column of the periodic table as the size of the anion increases.
