Dehydrogenative coupling of 4-substituted Pyridines catalyzed by diruthenium complexes
Coupling reaction of 4-substituted pyriclines via direct C-H bond activation was achieved by the use of diruthenium complexes 1 and 2. These reactions provide a variety of functionalized bipyridines in a selective manner without the formation of terpyridines.
