Crystal Structure of 2,12-Dichlorocyclododecanone

Abstract

The present crystal structure of 2,12-dichlorocyclododecanone was determined by X-ray analysis. The 12-membered ring has 422-symmetry, containing eight torsion angels having synclinal conformations of approximately 65° (average 68.05°); the other four torsion angels conforming antiperiplanar conformations are the average of 160.7°, respectively. The effects of the carbonyl group and the Cl atoms on the conformation of the ring are also discussed.
