New 2H-[1]benzothieno[3,2-b]pyrroles were synthesized by a [1,5]-sigmatropic shift of 3H-benzothienopyrroles. The dependence of the rearrangement on solvent and temperature was studied. The first merocyanine dyes based on both 3H- and 2H-benzothienopyrroles were synthesized and characterized by NMR- and UV/Vis spectroscopy, mass spectrometry, and X-ray crystallography.(© Wiley-VCH Verlag GmbH & Co
新的 2H-[1] 苯并噻吩并 [3,2-b] 吡咯是通过 3H-苯并噻吩并吡咯的 [1,5]-σ 位移合成的。研究了重排对溶剂和温度的依赖性。第一种基于 3H- 和 2H-苯并噻吩并吡咯的部花青染料被合成并通过核磁共振和紫外/可见光谱、质谱和 X 射线晶体学表征。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim,德国,2006 年)
