Intraanular phenyl-substituierte Phane - Synthese und dynamische Stereochemie

The synthesis and properties of phanes of different ring size, substituted intraanularly by phenyl groups, and of new biphenylophanes 3, 38 - 43 with "pseudo-syn/anti"-structure are described.Barriers for the hindered rotation of intraanular phenyl substituents have been determined by D-NMR spectroscopy. syn/anti conformers of -, -, - and metacyclophanes are found.A better method for the preparation of mediocyclic bisdisulfides is reported.The pyrolysis of (2-biphenylyl)methyl sulfones leads to fluorenes; pyrolysis of the thiosulfonic S-ester 44 yields bibenzyl and dibenzyl sulfide.

THE SYNTHESIS AND CONFORMATIONAL BEHAVIOUR OF 2,11-DITHIAMETACYCLOPHANES WITH INTERNAL PHENYL SUBSTITUENTS.

The synthesis of syn- and anti-9-methyl-18-phenyl- and anti-9,18-diphenyl-2,11-dithiametacyclophanes is described, together with their variable temperature 1Hmr spectra.Only partial rotation of the phenyl substituents (ΔGc50 kJ./mol) is believed to occur.
