용도

3-Bromothiophene is used in the preparation of derivatives such as thienylenic alpha, µ-diformyl-alpha-oligothiophenes and 3-lithiothiophene. It is also used in the synthesis of 3-lithiothiophene by reacting with n-butyllithium.

참고

Light sensitive. Incompatible with strong oxidizing agents, strong reducing agents and strong bases.

참조 문헌

Intermediate for preparation of 3-substituted thiophenes by the Grignard route: Arkiv. Kemi., 13, 295 (1959). Similarly, used in the synthesis of poly(3-alkylthiophenes) as conducting polymers: J. Org. Chem., 58, 904 (1993). Conditions have been described for the formation of 3-lithiothiophene, previously considered to be stable only under cryogenic conditions. It has been found to be stable in hexane solution at ambient temperature: Tetrahedron Lett., 35, 3673 (1994). Subsequent reaction with electrophiles leads to a variety of 3-substituted thiophenes.
