24.13 ( a ) The reaction is an acid base reaction. Phenol is the acid; sodium hydroxide is the base. ( b ) Sodium phenoxide reacts with ethyl bromide to yield ethyl phenyl ether in a Williamson reaction. Phenoxide ion acts as a nucleophile. ( c ) p -Toluenesulfonate esters behave much like alkyl halides in nucleophilic substitution reac- tions. Phenoxide ion displaces p -toluenesulfonate from the primary carbon. ( d ) Carboxylic acid anhydrides react with phenoxide anions to yield aryl esters. ( e ) Acyl chlorides convert phenols to aryl esters. ( f ) Phenols react as nucleophiles toward epoxides.
