Aplicaciones

Thiophene is an important building block in dyes, agrochemicals and pharmaceuticals synthesis. It is involved in the chloroalkylation reactions in 2,5-positions. It is also used to prepare butane by reduction with raney nickel, 2-vinylthiophene, dithienyl, and 2-halo thiophenes by reacting with halogens.

Notas

Incompatible with strong oxidizing agents and strong acids.

Referencias documentales

Metallation at the 2-position occurs readily with n-BuLi in ether (not readily in benzene). The 2,5-dilithio-derivative can be prepared in the presence of TMEDA: J. Chem. Soc., Perkin 1, 887 (1977), or with the superbasic combination of n-BuLi with KO-t-Bu: Synthesis, 316 (1988).
