| Abstract: | a-Bromoacetophenone and its ring-substituted derivatives were treated with silver powder and KI in anhydrous acetone to give a mixture of a,b-epoxy ketone, 1,2,3-triaroylcyclopropane, 2,4-diarylfuran, 1, 4-diketone and other products separated by column chromatog. The reaction of a-bromoacetophenone with PhCHO and 1,4-diphenylbut-2-en-1,4-dione in the presence of silver powder and KI in acetone gave epoxyketone I and cyclopropane II resp. |
