Description and Uses
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.
