Protonation of Methyl Substituted Phenols in Super Acids
Abstract
The protonation of a series of methyl substituted phenols and anisoles in FSO 3 H has been examined. When the para position of the phenol is unsubstituted, protonation was found to take place exclusively at this site. A methyl group on C-4 reduces the basicity of this carbon such that protonation on C-2, C-6 or oxygen can now compete with para protonation. Despite claims to the contrary, in FSO 3 H no significant amount of meta protonation was …
