Front Cover: Synthesis of 2,2’‐Bipyridines through Catalytic C−C Bond Formations from C−H Bonds (Eur. J. Org. Chem. 39/2021)

Abstract

The Front Cover shows – drawn in a cartoon‐style illustration – the different strategies to synthesize 2,2′‐bipyridines involving a C−H bond functionalization step. On the left side, the three approaches are inlaying in green lines. The catalysts (transition metal) are drawn in a bubble to illustrate the challenge of maintaining their catalytic activity while 2,2’‐bipyridines can coordinate and affect their properties. On the right side, the 2,2′‐bipyridine is designed as an allegory featuring a pink Cardoon flower for ligands and a bee for metals, showing their mutual bonding. Anne‐Sophie Pochet is thanked for taking the original photography on which this cover is built. More information can be found in the Minireview by J.‐F. Soulé et al.
