  Synthesis of functionalised cyclophanes with cage structure; via an unusual termolecular collision

  摘要：

  Coupling of the tetrathiol 11 with two equivalents of the dibromide 6,7 and 8 under high dilution technique in the presence of KOH in benzene - ethanol afforded the cyclophanes 1a, 1c & 1b respectively. Similarly cyclophane 1d was obtained from the tetrathiol 11 and tetrabromide 9.

  Synthesis and structural analysis of isomeric pyridinophanes and thiacyclophanes

  摘要：

  A one-pot synthesis of structurally isomeric tetrathiacyclophanes through four-centre coupling reactions of suitable bromides and thiols is reported. The structures of the isomers were confirmed by spectroscopy and XRD analysis. Single crystal X-ray analysis reveals interestingly shaped molecular structures with large cavities.

  Cyclophanes of the type 1 and 2, with large cavity sizes, have been synthesized from the corresponding dichloride 8 or 8a and o-xylene-alpha,alpha'-dithiol (9), p-xylene-alpha,alpha'-dithiol (10), or m-terphenyldithiol (11). Similarly, cyclophanes of the type 3 with intra-annular functionality have been obtained by the coupling of the corresponding dithiol 15 or 19 and m-terphenyl dibromide 5, 5a, 5b, or 5c. With the aim of introducing multifunctionality, cyclophanes of the type 21 and 23 were prepared from 3,5-bis(mercaptomethyl)anisole or 3,5-bis(mercaptomethyl)phenol and the corresponding substituted m-terphenyl dibromide Bb or 5c. Cyclophanes 24, 24a, 24b, and 32, with a new type of cage structure, have been obtained by the coupling of the corresponding tetrathiol as with 2 equiv of the dibromides 5c, 5a, and 5b or 1 equiv of the tetrabromide 31, respectively. Further, the sodium salts of the cyclophanes 3c, 21, and 24b were completely characterized by H-1 NMR spectroscopy. XRD analysis of the cyclophane 21 revealed the presence of an ethanol molecule inside the cavity, indicating the facile formation of a host-guest complex.
