Abstract
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. Tetrathio [6] 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 ...
