Salt effects resulting from exchange between two ion pairs and their crucial role in reaction pathways
Article Abstract:
An added salt shapes the behavior of an ion pair in a chemical reaction, whether it is an electron transfer (ET) process or an electrophilic/ nucleophilic one. Depending on the solvent's polarity, the nature of interacting ions and the dissociation kinetics of the geminate ions, the new ions affect the extent and selectivity of the reaction. This is specially true with contact ion pairs found in low dielectric constant solvents, where they act as catalysts. Of special interest is their effect on photolytic ET reactions, which may find application in energy storage devices.
