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.
标题化合物已通过涉及 4,4'-(2,5-呋喃二基)双 (1-溴-2-丁酮) 与硫化钠的环化,然后与乙二醛缩合得到 1,11-二氧六环 [ 3.3](2,5)呋喃(2,5)噻吩,一种新的分子内CT复合物。[3.3](2,5)噻吩的溶液含有反和顺构象异构体,比例约为。20:1,如 VT-NMR 研究所示。
