Facile synthesis of [1]benzothieno[3,2-b]benzothiophene from o-dihalostilbenes
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 (Na(2)S center dot 9H(2)O) or sodium hydrosulfide hydrate (NaSH center dot nH(2)O) and sulfur is described along with plausible reaction paths in this intriguing reaction.
