General description

2-Bromothiophene undergoes metalation-alkylation reaction with various electrophiles to form various 5-alkylated 2-bromo products. It undergoes coupling with 4-bromo allyl phenyl ether to form allyl phenyl thiophene ether, which is a novel potential dielectric material for organic thin film transistors.

Application

2-Bromothiophene has been used in electrochemical reduction of a number of mono- and dihalothiophenes at carbon cathodes in dimethylformamide containing tetramethylammonium perchlorate by cyclic voltammetry and controlled-potential electrolysis.
