Talk:Electrophilic halogenation

I disagree with the statement:

"Halogenation of phenols is faster in polar solvents due to the dissociation of phenol, with phenoxide ions being more susceptible to electrophilic attack as they are more electron-rich."

There is no reference given supporting this claim. I doubt that the dissociation of phenol to phenoxide happens to a significant extent in non-basic polar aprotic solvents. A much more likely explanation is that a polar solvent stabilizes the polar transition state relative to in non-polar solvents, thus speeding the reaction.
