Application
3-Iodothiophene was used in the synthesis of 3-thienylzinc iodide via reaction with zinc, followed by coupling with aryl halides. It was also used in the preparation of 3-(perfluorooctyl)thiophene, required for the synthesis of poly(3-perfluorooctylthiophene) conjugated polymer.

The reduction of 2-bromo- and 3-bromothiophene with calcium powder gives impure thienylcalcium complexes due to interference of various subsequent metalation and calcium-halogen exchange reactions as well as ether degradation. Therefore, calcium-iodine exchange succeeds via the reaction of trimethylsilylmethylcalcium halide with
