The bromo-substituent can be readily displaced by methoxide in methanol in the presence of a Cu(I) catalyst: Synth. Commun., 20, 213 (1990). For coupling reaction with Thiophene-2-thiol, B22642, in the presence of Cu2O, to give 2,2'-dithienyl sulfide, see: Org. Synth. Coll., 6, 558 (1988).

Allylic alcohols are thienylated by means of a Heck-type, Pd-catalyzed coupling reaction; the products are ketones formed by rearrangement: Chem. Lett., 423 (1977). Coupling with iodoarenes can be induced at the 5-position by the use of a palladium(II) catalyst in the presence of silver nitrate and potassium fluoride, providing access to 5-aryl-2-bromothiophene derivatives, which may be further elaborated by reaction with the available 2-bromo-substituent: Org. Lett., 7, 5083 (2005).
