Abstract: Abstract Phenylmethylidene-bis(pyrrolo[2,3-b]quinoxaline) derivative (1) was synthesized by the reaction between the 3-thiobenzoylpyrrolo[2,3-b]quinoxaline (SPQ) and a secondary amine or NaOH in DMF solution. The obtained compound was characterized by single crystal X-ray diffraction, which indicated the… read more here.
