During the action of an anhydrous solution of perchloric acid in alcohol on methyl aryl ketones in ethyl orthoformate open-chain carboxonium salts (derivatives of the 1,5-diaryl-2-pentene-1,5-dione) were formed instead of the 2,6-diarylpyrylium perchlorat

In the reaction of ketovinylnitroamines with various nucleophiles substitution of the nitroamine group by the nucleophilic reagent took place in all cases.The addition of bromine at the double bond of ketovinylnitroamines took place with difficulty after prolonged heating in benzene or carbon tetrachloride.

The treatment of 1,1,1,3-tetrachloro-3-phenylpropane with alkali in ethanol affords ethynyl phenyl ketone and its acetal in good yields.This reaction proceeds through the elimination of hydrogen chloride and an efficient 1,3-proton transfer catalyzed by base.Ethyl cinnamate is obtained in only 2percent yield.
