| Uses | manufacture of pharmaceuticals, thioindigo. |
| Uses | Benzo[b]thiophene is used in the preparation of 2-thianapthenylphenyllithium, via metalation by n-butyllithium. It is used in organic as well as pharmaceutical industry as a component in the synthesis of raloxifene, a breast cancer therapeutic, or hydrodesulfurization reactions. |
| Uses | Thianaphthene may be used in the preparation of 2-thianapthenylphenyllithium, via metalation by n-butyllithium. |
| Application | Thianaphthene may be used in the preparation of 2-thianapthenylphenyllithium, via metalation by n-butyllithium. Reaction of ethyl diazoacetate with thianaphthene has been reported. |
| Definition | ChEBI: 1-benzothiophene is a benzothiophene and a member of 1-benzothiophenes. |
| Synthesis Reference(s) | Journal of the American Chemical Society, 69, p. 2008, 1947 DOI: 10.1021/ja01200a053 Tetrahedron, 27, p. 1253, 1971 DOI: 10.1016/S0040-4020(01)90874-9 |
| General Description | Reaction of ethyl diazoacetate with thianaphthene has been reported. |
| Purification Methods | 1-Benzothiophene has the odour of naphthalene. If the IR spectrum is not very good, then suspend it in a faintly alkaline aqueous solution and steam distil it. Extract the distillate with Et2O, dry the extract (CaCl2), filter, evaporate the solvent and fractionate the residue. The distillate sets solid. The sulfoxide has m 142o, the picrate has m 148-149o (yellow crystals from EtOH) and the styphnate has m 136-137o.
