Silica gel-assisted synthesis of benzo[b]thiophenes from o-(alkylsulfanyl)(ethynyl)benzenes
A variety of 2-substituted benzo[b]thiophenes were prepared from o-(alkylsulfanyl)(ethynyl)benzenes in the presence of silica gel under thermal conditions. Tertiary alkyl-substituted sulfanyl derivatives gave good results. Methylsulfanyl-substituted precursors also afforded benzo[b]thiophenes at hig...
