Abstract

Ethylene and simple vinyl esters add to cyclopentadienones without accompanying decarbonylation, provided a low temperature is employed. An excess of the ethylenic component is essential for good yields. Anhydrous aluminum chloride catalyzes the addition of ethylene. The same catalyst also brings about a rearrangement of 1, 2, 3, 4tetraphenylbenzene to the 1, 2, 4, 5-isomer, but the rate is too slow to be a complicating ...
