Abstract: The reactions of 2,4,4,6-tetraaryl-4H-thiopyrans 1 or 3 with chlorine at room temperature proceed rapidly to give the corresponding 3,5-dichloro derivatives 2 or 4 and then slowly to give 6,7-benzo-1,3,5-triaryl-4,8,8-trichloro-2-thiabicyclo [3.2.1]octa-3,6-dienes 5 or 6; the structure of 6 has been determined by X-ray analysis.
