Development of and Mechanistic Insights into Palladium-Catalyzed C-H Arylation Reactions. [PDF]
Biaryls are important targets for numerous applications in organic synthesis. As a result, the development of metal-mediated aryl cross-coupling has been extensively studied. The disadvantage of this approach is the requirement for each coupling partner
