Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst

Chemistry – A European Journal, EarlyView.
While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere

Urothermal Synthesis of Luminescent Alkaline Earth MOFs

Chemistry – A European Journal, EarlyView.
The e‐murea derivative (1,3‐dimethylimidazolidin‐2‐one) was employed as solvent for the urothermal synthesis of a series of nine AE MOFs featuring luminescence in the crystalline state with remarkable quantum yields ranging from 0.45 to 0.84. ABSTRACT The urothermal approach in 1,3‐dimethylimidazolidin‐2‐one (e‐murea) was employed for the successful ...

The Future of Foundation Machine Learning Potentials and DFT in Homogeneous Catalysis: Competition or Synergy?

Chemistry – A European Journal, EarlyView.
Machine‐learning potentials are increasingly taking on the exploratory tasks of homogeneous catalysis, enabling rapid conformer sampling and reaction‐space mapping. However, when selectivity depends on subtle electronic effects, electronic‐structure methods remain essential.

Cationic Permethylated Cyclodextrins Capable of Self‐Assembling Into Linear Nanostructures in Water

Chemistry – A European Journal, EarlyView.
A quaternary ammonium bridge equipped with a lipophilic substituent in permethylated cyclodextrins suppresses undesired supramolecular interactions and promotes controlled, directional head‐to‐tail self‐assembly into well‐defined linear nanostructures.

Catalyst‐Free Cyanation of Arenes by Acetonitrile in a Plasma–Liquid Microreactor

Chemistry – A European Journal, EarlyView.
An original approach of arylnitrile synthesis was developed by generating an argon plasma in contact with solutions of arene in acetonitrile within a gas‐liquid microreactor. Plasma activation of acetonitrile generated cyano radicals, enabling a catalyst‐free C‐H cyanation of arenes.

Synthesis and Functional Properties of Fluorinated Phosphonate‐Substituted Porphyrins: Excellent Photosensitizers and Robust Precursors for Photoactive Langmuir–Schaefer Films

Chemistry – A European Journal, EarlyView.
This is a comprehensive study of new family of high functionalized meso‐tetraarylporphyrins. A synthetic approach to phosphonate‐substituted fluorinated porphyrins was developed. These compounds were investigated with respect to singlet oxygen generation and photostability.

Les clusters moléculaires. Applications en catalyse homogène et hétérogène Molecular Clusters. Applications in Homogeneous and Heterogeneous Catalysis

Oil & Gas Science and Technology, 2006
Le présent article ne prétend pas être une étude bibliographique complète. II ne s'agit que d'une synthèse dont le but est l'introduction à un secteur de la chimie encore jeune et surtout très vaste et plein d'avenir.

Covalent Insertion of a Mn(Salen) Type Complex in Cross‐Linked Protein Crystals: Design of an Enantioselective Artificial Epoxidase

Chemistry – A European Journal, EarlyView.
An Artificial metalloenzyme was designed by a Michael addition between a MnSalen complex and a cysteine residue within NikA crystals. The heterogeneous catalyst was found capable of an enantioselective and stereospecific epoxidation of cis‐β‐methylstyrene in cristallo.
