Substituents over the four-positions of the thiophenol substrates led to drops around the reaction yields (5i to 5k). Naphthyl and heteroaryl mercaptan substrates usually gave the desired benzofuran items in reasonable to superior yields (5l to 5o). Benzylthiols may work nicely On this radical coupling approach, although the yields in https://revivalschem.com/product/buy-4-ho-met-20-mg-pellets/
