摘要

A convenient one-pot synthesis of [1] benzothieno [3, 2-b] benzothiophene from readily available o-dihalostilbenes using combined reagents of sodium sulfide nonahydrate (Na2S· 9H2O) or sodium hydrosulfide hydrate (NaSH· nH2O) and sulfur is described along with plausible reaction paths in this intriguing reaction.
