Abstract
The oxidative insertion of readily available zinc dust into the carbon-bromine bond of 2,5-dibromo-3-hexylthiophene was efficiently achieved to provide 2-bromo-3-hexylthien-5-ylzinc bromide (I), which was utilized for the preparation of highly regioregular poly(3-hexylthiophene) (P3HT) in the presence of catalytic amounts of Ni-catalyst.
