Abstract
The title compounds (I) in benzene solution are changed by the action of aqueous or ethanolic solution of potassium hydroxide at room temper ature to the mixtures of compounds II-V. The ratios of products depend on the substitution of educts I and on the reaction conditions. By th e action of solid potassium hydroxide on the compounds I or II, the co mpounds III are formed.
