摘要：

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.
