Systems containing Sulphur as the only Heteroatom

Systems containing Sulphur as the only Heteroatom. - A variety of sulphur-containing cyclophanes were synthesized by the dilution principle, using an improved apparatus. The equipment will prove valuable in the preparation of many macrocyclic systems. The iron-catalysed reaction between bis-(2,4-dimethoxyphenyl) sulphide and S2CI2 gave four macrocyclic systems, including (47). The formation of (47) occurs by the unusual electrophilic cleavage of C-aryl-S bonds.
