| Abstract: | Reactions of 1,1-di(2-naphthyl)-2,2-dichloroethene and 1,1-di(2-benzothienyl)-2,2-dichloroethene with sulfur at 220–225 °C resulted in hitherto unknown oligothiophenes. Tetrathio6]helicene was synthesized from 1,1-di(3-benzothienyl)-2,2-dichloroethene. Preparative pathway to helicene involving intramolecular ring closure of dithiol derived from 1,1-di-(3-benzothienyl)-2,2-dichloroethene was developed as an alternative to high temperature synthesis. |
