Abstract

To circumvent the ethoxy exchange, the cleavage was run in benzene at 50" C where yields of pure 2 of up to 84% were realized. On refluxing in henzene, about 8% of dicleaved material, 12, was obtained, similar to that in acetophenones." Identification of 12 was from conversion to its methylenedioxy derivative. 13.
