Abstract
Thiete sulfone (1) and tetracyclone react in refluxing m-xylene to yield 1, 2, 6, 7- tetraphenylcycloheptatriene (65%, 2) and a bicyclic ketone (15%), 1, 5, 6, 7- tetraphenylbicyclo [3.2. l] octa-2, 6-dien-~-one (3). When 1, 2, 3, 4- tetraphenylcyclopentadiene and thiete sulfone are refluxed in m-xylene, a 77% yield of the Diels-Alder adduct is obtained in addition to 1, 5, 6, 7-tetraphenylbicyclo [3.2. l] octa-2, 6- ...
