Hydroaminomethylation (HAM) is a very straightforward reaction for amine synthesis usually performed in hard reaction conditions and using nonsustainable solvents. The use of micellar and microwave catalysis involves switching from the traditional HAM reaction mechanism to the efficient regioselective synthesis of linear amines. The cover is the result of a collaboration with artist Vanessa Rusci (https://www.vanessa-rusci-arte.com) in the context of a project for scientific dissemination.

The Cover Picture shows a series of rhenium(I) triscarbonyl complexes with a carbodiphosphorane-based tridentate ligand between two facades of the MLU Weinberg Campus. The [PCP] and [PC(H)P]+ coordination sides in the carbodiphosphorane ligand open a window to versatile coordination modes toward the ReI center. In this context the colored globes, highlighting the large impact of modern pincer chemistry, illustrate the meridional configuration of the carbodiphosphorane pincer-ligand in the reported rhenium complex to be located in the thermodynamic ground floor. Yet a facial arrangement was initially observed upon coordination to ReI, it is located in the upper floors of the building (https://doi.org/10.1002/zaac.202100151).

The Pincer Platform Beyond Classical Coordination Patterns (Eur. J. Inorg. Chem. 41/2020)
Dr. Matthias Vogt, Prof. Dr. Robert Langer
Pages: 3884
First published: 20 October 2020

The Front Cover shows the  analogy between the  arrangement in pincer-type ligands and simple  geometrical compositions,  which can easily be deconstructed into their  building blocks. Using  such a deconstructive approach, the present  Minireview categorizes  pincer-type ligands according to the binding properties of the involved  ligating fragments and reflects achievements beyond well-established  definitions. More information can be found in  the Minireview by M. Vogt and R. Langer   .
