Notizen:
Dithiametacyclophanes with Triple BondsSchemes 1 and 2 show the syntheses of dithia[8]metacyclo-phanes 4a-d and tetrathia[m.n]metacyclophanes 9, 10 by cyclization reactions applying the cesium effect. All these cyclophanes contain C - C triple bonds which influence the molecular dynamics; especially the halogen substituents in 4b-d obstruct the topomerization.
