Heterocyclic cyclophanes. Part I. Thiacyclophanes from thiols
Abstract
The formation of thia [5,5]cyclophanes from carbonyl compounds and aromatic dithiols has been re-investigated. The synthetic procedure was improved and crystalline thiacyclophane oligomers were also isolated. N.m.r. and u.v. data of the thiacyclophanes were obtained and their usefulness in determining the structures is discussed.
