Substitution reactions of phenol

WebReaction with Bromine. Unlike benzene, phenol is able to undergo electrophilic substitution with halogens at room temperature, without the need for a halogen carrier. When bromine … WebAnother such substitution reaction is the isotopic exchange that occurs on mixing an alcohol with deuterium oxide (heavy water). This exchange, which is catalyzed by acid or base, is very fast under normal conditions, since it is difficult to avoid traces of such catalysts in most experimental systems. 2 R–O–H + 2 Na 2 R–O (–) Na (+) + H 2
