4. For example, the cleavage ratios reported by Hall and Horner(1)are compromised by nucleophilic displacement because they used methylsulfonium salts and tetrabutylammonium bromide as the supporting electrolyte in acetonitrile. As the temperature was increased in their electrolytic experiments, the amount of methyl cleavage increased, as expected for a competing SN2 reaction.
