Abstract
An oxidative homocoupling method of synthesizing certain 2,2'-bithiophenes from thiophenes using oxygen as the terminal oxidant is disclosed. In non-limiting examples, the method uses oxygen along with a catalytic system that includes palladium, an assistive ligand, and a non-palladium metal additive to catalyze one of the following reactions: Associated catalytic systems and compositions are also disclosed.
