Chemistry A European Journal

P−H bond activation is an important step in many catalytic applications involving the formation of new P−C bonds. The icebreaker “RV Bond Activation”, which symbolizes our carbene complexes depicted by the constellation in the sky, is able to easily break P−H bonds via the carbene linkage. The splitting of phosphines into protons and phosphide fragments (depicted as ice shards flying away) occurs even at low temperatures.

The Front Cover shows the structure of the newly reported, isolated metallated ylide. Due to the high negative charge at the ylidic carbon center this compound is „on fire“, but can be stabilized by smart molecular design. Structure analyses of the different alkali metal complexes combined with computational studies provide insights into the electronic structure of the compounds.

Chemical Science Inside Cover

Showcasing research from Professor Gessner’s laboratory at Ruhr-University Bochum, Germany
Towards the rational design of ylide-substituted phosphines for gold(I)-catalysis: from inactive to ppm-level catalysis
Systematic studies on the impact of different aryl substituents in the backbone of ylide-substituted phosphines reveal that steric bulk leads to a boost of the catalytic activity in gold catalysis.

Chemistry - A European Journal

Ylide‐substituted phosphines (YPhos) are excellent ligands for Pd‐catalyzed cross‐coupling reactions. This work examines the impact of different ligand substituents and the use of defined precatalysts on the catalyst activity in room temperature C−N couplings. Increased selectivities and activities are obtained with the backbone‐modified joYPhos ligand which exhibits extremely high activities (TOF>10 000 h−1) and productivities for the coupling of a variety of amines and aryl halides.

Organometallics

A new PCcarbeneS ligand has been designed for the stabilization of nucleophilic late transition metal carbene complexes for bond activations via metal–ligand cooperation. This ligand combines previous approaches to such complexes by using different stabilizing effects. O–H and N–H bond activations, including ammonia, could thus be realized by additions across the M=C bond. The cover art illustrates the design of the new ligand by mixing existing concepts and shows molecules, which are readily activated by the carbene complex.

Power to phosphines Phosphines are one of the most utilized types of ligands in catalysis and their advancement is indispensable for further developments in this field. In their communication,V. H. Gessner et al. demonstrate that ylide functionalization is a powerful tool to increase the donor strength of phosphines. The YPhos ligands obtained are easy to synthesize, more electron‐rich than classical phosphines or even NHCs, and allow for improved catalytic activity in gold catalysis.

Chemistry - A European Journal

Metal/Fluorine carbenoids are usually highly reactive and temperature‐sensitive compounds. It has now been demonstrated that even these compounds can be stabilized and isolated at room temperature. Manipulation of the strength of the metal–fluorine interaction turned out to be decisive for stability control. As such, the lithium compounds are considerably more reactive than their heavier congeners, which thus also provides a tool for reactivity control.

The reactivity of s‐block metal organyl compounds generally increases when going down the group of the periodic table. However, V. H. Gessner and S. Molitor report in their Communication the reverse of this trend for alkali metal carbenoids by replacement of lithium by sodium or potassium, allowing for unexpected control of the stability and reactivity of these usually highly reactive species. This is depicted by a soccer player on the Na/K team who kicks the Li out of the molecular structure.

The cover picture shows the versatility of methandiide‐based carbene complexes with respect to the bonding situation and the metals applicable. Although only a handful of suitable methandiide precursors are available, they have led to a myriad of carbene‐like complexes with metals covering the whole periodic table. The flexible bonding situation – illustrated by the two springs connecting the carbon and metal atoms – determines the unique electronic properties and reactivities of these compounds.
