Abstract

The X‐ray structures of dibenzo[ce]‐1,2‐dithiine, dibenzo[ce]‐1,2‐dithiine‐5,5‐dioxide, diben‐ zo[ce]‐1,2‐dithiine‐5,5,6‐trioxide, and dibenzo[ce]‐1, 2‐dithiine‐5,5,6,6‐tetraoxide are reported and compared with the related “constrained'' naphthalene deri‐ vatives. The S‐S distances vary upon oxidation of the S centers in the order S‐S < SO‐S > SO~2~‐S < SO~2~‐SO > SO~2~‐SO~2~ i.e. the most oxidized sulfur atoms do not lead to the longest bond lengths. © 2005 Wiley Periodicals, Inc.
