✦ Synopsis

The conjugative interaction between the two terminal groups in title quinarenone 2 and its ckloro-and methoxy-derivatives were evaluated, proving that the diatropicity of the seven-membered ring is a little larger in 2 than in tropone. Some of these quinarenones are aZso found to exist in equilibriwn with their oligomers and show unexpectedly Zow barriers of rotation about the intercyclic bond.
