Abstract

Abstract: The Diels-Alder reaction of tetrachlorocyclopentadienone ketals with acetylenic dienophiles yielded 1, 2, 3, 4-tetrachloronorbornadienone ketals, some of which decomposed in situ and some were obtained in pure form. When pyrolyzed, these compounds gave two kinds of aromatic products: those which had lost the ketal bridge and those which had retained it in the form of an ester function. Both ionic and radical ...
