2. A type of organic compound in which at least one hydroxyl group is bound directly to one of the carbon atoms of an aromatic ring. Phenols do not show the behavior typical of alcohols. In particular they are more acidic because of the electron-withdrawing effect of the aromatic ring. Th...
Phenols are much more acidic than alcohols becausethe negative charge in the phenoxide ion is not localized on the oxygen atom, as it is in an alkoxide ion, but is delocalized-it is shared by a number of carbon atoms in the benzene ring. Why is phenol called carbolic acid? Because ofthe...
Michael addition of di- and tri-hydric phenols to N-cinnamoylimidazoles followed by a lactonisation offers a route to 4-aryl-3,4-dihydrocoumarins and their [f]-benzologues <00S123>. The lactonisation of the naphthoquinone derivative 66 is sensitive to the acidic cyclising medium and it is...

(14and15). The hydroxymethylmelamines are only stable in strongly alkaline aqueous solutions. Their reaction with alcohols gives alkyl ethers, which are soluble inorganic solventsand are stable. If heated under slightly acidic conditions, these materials lose alcohol and form internuclear bridges by ...
