Powerful annulation fuses polyaromatics
More than a century ago, chemists discovered the homocoupling of aryl halides, in which a copper catalyst convinces twin halogen atoms to give up their positions to bring together two aryl rings. This mighty dimerization reaction has long dominated biarene synthesis. Now, scientists are offering an upgrade. A research team at Nagoya University, led by Kei Murakami and Kenichiro Itami, has developed an annulative dimerization . . .
