Webstabilized by hydrogen bonding, the pK of water in water would be about 28. This latter pK value would be the appropriate one to use when 'comparing water with.non-hydroxylic acids in.a non-hydroxylic solvent. " Alkali metal hydroxides are very strong bases, but their base strengths are greatly reduced by dissolving them in hydroxylic solvents Webhydrogen bromide (HBr–THF) complex [6], and Lewis acid. In recent years, the ionic liquids [7–13] have been used as the Diels–Alder reaction medium instead of con-ventional organic solvents. A good solubility of the cata-lysts has been of crucial importance in their applications. The catalysts of these cycloaddition reactions are fre-
