route involving cyclization of 4,4′-(2,5-furandiyl)bis(1-bromo-2-butanone) with sodium sulfide followed by condensation with glyoxal to give 1,11-dioxo[3.3](2,5)furano(2,5)thiophenophane, a new intramolecular CT complex. A solution of [3.3](2,5)thiophenophane contains anti and syn conformers in a ratio of ca. 20:1 as shown by a VT-NMR study.
