Direct evidence for a carbon–carbon one-electron σ-bond
2024 / NatureCovalent bonds share electron pairs between two atoms and make up the skeletons of most organic compounds in single, double and triple bonds. In contrast, examples of one-electron bonds remain scarce, most probably due to their intrinsic weakness1,2,3,4. Although several pioneering studies have reported one-electron bonds between heteroatoms, direct evidence for ...
