Abstract

Abstract One-pot double couplings of dibromothiophenes have been investigated. Standard Suzuki couplings work well for 2, 4-dibromothiophene, but are much more sensitive to steric effects in the case of 2, 3-dibromothiophene. By using the recently reported potassium borates, though, good yields for both dibromothiophene isomers can be achieved.
