Structures and reactivities of ethylene dication electrophiles

1,2-Dicarbonyl compounds such as 2,3-butanedione reacted with benzene in the presence of a strong acid, trifluoromethanesulfonic acid, to give gem-diphenylated ketones in high yield. The monoxime derivative of 1,2-diones also reacted with benzene in the a

Acid-catalyzed Reactions of 1,2-Dicarbonylethanes with Benzene. Ethylene Dication Electrophiles.

1,2-dicarbonyl compounds reacted with benzene in the presence of a strong acid, trifluoromethanesulfonic acid, to give gem-diphenylated ketones in high yields.The reaction was accelerated when the acidity of the medium was increased, supporting involvement of O,O-diprotonated 1,2-dicarbonyl species (i.e., 1,2-dihydroxyethylene dications) as the active electrophiles.
