A new cyclophane, 10,20-dibromo-2,3,12,13-tetrathia[4.4]metacyclophane (l), has been synthesized by the oxidative coupling reaction of 2,6bis(mercaptomethy1)-1-bromobenzene with 12. Both syn and anti isomers of 1 can be isolated at room temperature. The thermal sulfur extrusion reaction of anti-1 wi
