A Message to Our Readers, Authors, and Reviewers
We recognize that the COVID-19 pandemic is affecting everyone’s daily lives and the global research community in unprecedented ways. Although some research activities are slowly resuming, many institutions remain closed, with researchers working from home under unusual circumstances. Our editorial teams also continue to work remotely.
Throughout these challenging times, we aim to support our scientific community in any way possible. Given the possible disruption of experimental work, we kindly ask our reviewers to bear in mind that some experiments may be hard to do these days. Now more than ever, it is important to mention clearly which suggestions you consider to be essential. We are aware that authors and reviewers are doing their best to revise and review manuscripts given these circumstances and should you need extra time, please contact the corresponding editorial office without hesitation.
Please accept the best wishes of our editorial teams for your ongoing health and wellbeing.
25th Anniversary
2020 marks the 25th anniversary of Chemistry—A European Journal. We will be celebrating this throughout the year with special article collections, games, competitions, and much more. Find out more.

A new borylstannane was invented to achieve the radical borylation of various alkyl radical precursors. Various alkyl radical precursors including isocyanides, selenides, sulfides, and alcohol or carboxylic acid derivatives are found to be applicable to the present borylation. The cover picture of a trapeze performer (borylstannane) grasping the arms of a clown (a radical) depicts the transition state of the radical borylation. The arms of the performer show a vacant p-orbital on the boron atom of the borylstannane, which intends to capture the clown's arms (radical), and the fallen hat depicts a stannyl radical. More information can be found in the Communication by K. Suzuki, Y. Nishimoto, and M. Yasuda. on page 3968.
A light-harvesting antenna model made of three mutually axially coordinated zinc porphyrin molecules is reported in this work. With an energy gradient incorporated, energy transfer only occurs from porphyrin molecules specializing in light absorption to a porphyrin molecule as a charge separation center. The latter molecule is a directly linked porphyrin/ferrocene dyad. The image implies that the light energy is funneled into the lower energy porphyrin/ferrocene dyad with no unfavorable back energy transfer. More information can be found in the Full Paper by J. Otsuki et al. on page 4053.
A kind of “street art lab-journal” on a graffiti wall is depicted in the cover image. The left side shows a table where the already obtained d/f-polypnictides (P, As) are ticked, while Sb is still marked as an unsolved task. According to this, the right side shows the reaction equation, which represents the pathway to the solution of the task and finally the resulting, artistically highlighted, compound. On the bottom you can see the ′spray cans of the elements′, which are required for this compound. More information can be found in the Communication by P. W. Roesky et al. on page 4064.

Abstract
Like a rocket: An extremely fast nickel‐mediated thiocarbonylation reaction yielding 2‐pyridyl thioesters provides for a convenient carbon‐13 labeling approach to the preparation of structurally elaborate aliphatic carboxamides, including both small molecule and peptide APIs. The methodology could have implications for carbon‐11 and carbon‐14 labeling of carboxamides. Images created using Mol*: D. Sehnal, A. S. Rose, J. Kovca, S. K. Burley, S.

Abstract
By using a very simple ligand‐free palladium‐catalyst and without directing group installation, the less‐acidic β‐C−H of pyrazoles is regioselectively arylated (up to 98 %) conserving untouched α‐C−H bonds.

- 24 February 2021
Abstract
Molecular complexes have shown strong potential to mediate N2 functionalization reactions under mild conditions while providing a straightforward understanding of reaction mechanisms. This Review emphasizes the strategies for N2 reduction and functionalization using transition metal and actinide complexes according to their proposed reaction mechanisms and presents the main examples of stoichiometric and catalytic N2 functionalization reactions. For more details see the Review by V. Mougel et al. on page 3892 ff.

Abstract
Intelligent stimuli‐responsive DNA nanostructures have attracted increasing attention for biological and biomedical research owing to their promising native biocompatibility, programmability, multifunctionality, responsiveness to biological cues, and easy implementation for designing new materials. The most recent progress in this fast‐growing field is described in the Minireview by X. Liu et al on page 3929 ff.

Abstract
Elementary my dear Helicene: An old‐school plastic molecular model of the supramolecular assembly formed by poly‐adenosine with cyanuric acid reveals a non‐planar spiral helicene structure, held together by alternating Watson‐Crick and Hoogsteen hydrogen bonds. In silico molecular model dynamic simulations provide further support suggesting that the helicene structure can accommodate a dyad and/or triad of poly‐A strands. The findings have implications for the role of small molecules in nucleic acid‐structural reorganization and pre‐RNA world paradigms. For more detail see the Full Paper by R. Krishnamurthy et al. on page 4033 ff.

Abstract
Bond—Single Bond! A new set of single‐bond covalent radii for Z=1–118 is obtained from a self‐consistent fit. Its mean‐square deviation, δ, is under 3 pm. For specialized sets, like those shown here, δ can be lowered below 1 pm.
Full PaperModulated Synthesis of Zr‐Based Metal–Organic Frameworks: From Nano to Single Crystals

- 5 May 2011
Abstract
Modulated crystallinity: Nanocrystals of varying sizes of UiO‐66 (Zr–bdc metal–organic framework (MOF)), individual microcrystals of UiO‐67 (Zr–bpdc MOF) and the first single crystal of a Zr‐based MOF containing a long linker (Zr–tpdc–NH2 MOF) were obtained (see figure). The last one allowed, for the first time, a single‐crystal diffraction study of a Zr‐based MOF. (H2bdc: terephthalic acid, H2bpdc: biphenyl‐4,4′‐dicarboxylic acid, H2tpdc: terphenyl‐4,4′′‐dicarboxylic acid.)

- 10 July 2012
Abstract
Unprecedented accuracy for computed association free enthalpies of supramolecular host–guest complexes (some examples are shown here) in solution has been achieved by a combination of high‐level quantum chemical procedures. The approach is quite general, includes all basic physical effects quantitatively and requires no special empirical adjustments.

Abstract
Carbon‐rich‐quick scheme: A carbon‐rich solid product made up of uniform micrometer‐sized spheres of tunable diameter has been synthesized by the hydrothermal carbonization of saccharides. These microspheres possess a core–shell chemical structure based on the different nature of the oxygen functionalities between the core and the outer layer (see figure).
