The reaction of 1-benzothiophen-3(2H)-one hydrazone with various ketones under different conditions has been studied and a convenient method has been proposed for the synthesis of thienopyrrole derivatives. The method is applicable to the preparation of 1H- and 3H-benzothienopyrroles with a range of substituents. Georg Thieme Verlag Stuttgart.
Isomerization of 3H- to 2H-[1]benzothieno[3,2-b]pyrroles and synthesis of the first merocyanine dyes based on them

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-benzothienopyrrole
