Thianaphthene Chemical Properties,Uses,Production

Chemical Properties

WHITE TO RED CRYSTALLINE LOW MELTING SOLID

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.

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.
