Front Cover: Stabilities and Limitations in the Reactivity of Phosphorus Ylide-Based Aluminum– and Gallium–Carbon Ambiphiles: A Combined Experimental and Computational Approach (Eur. J. Inorg. Chem. 16/2025)

Abstract

The Front Cover shows a sketchpad with the structure of the formal methanol activation product of an aluminum–carbon-based ambiphile that is formed by the elimination of ammonia. A water molecule is shown above the eliminated ammonia molecule, indicating that replacement by water can also be realized. On the left, other small molecules that do not react with the title compounds are shown. The product of trimerization of phenyl isocyanate, for which the ambiphiles act as catalysts, is shown on the left. To the right are shown the insertion products of carbon dioxide and acetonitrile. The ticked reaction product with carbon dioxide can be realized, the crossed-out acetonitrile product cannot. The reaction path bottom right shows that the insertion process of acetonitrile is endergonic overall and rather high activation barriers are predicted. More information can be found in the Research Article by I. Fernández, F. Breher and co-workers (DOI: 10.1002/ejic.202500165).
