Thianaphthene Chemical Properties,Usage,Production

Chemical Properties

WHITE TO RED CRYSTALLINE LOW MELTING SOLID

Uses

Benzo[b]thiophene has application in organic as well as pharmaceutical industry as a component in the synthesis of Raloxifene, a breast cancer therapeutic, or hydrodesulfurization reactions.

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.

Uses

manufacture of pharmaceuticals, thioindigo.

Definition

ChEBI: 1-benzothiophene is a benzothiophene and a member of 1-benzothiophenes.

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.

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.
