(2‐Phosphinophenyl)aluminum Dichloride Complexes as Intramolecular Al/P Frustrated Lewis Pairs for Ketone, Ester, and Imine Activation

Chemistry – A European Journal, EarlyView.
Three 2‐phosphinophenylaluminum dichloride complexes were synthesized and characterized as novel intramolecular FLPs. These FLP systems exhibit high Lewis acidity and effectively activate challenging substrates including aliphatic ketones, imines, and esters. DFT analysis revealed that strain release and Al–P dynamics govern their reactivity. Abstract (

Decoupling Redox Potentials and Excited State Energies in Substituted Chromium(III) Chromophores

Chemistry – A European Journal, EarlyView.
Redox and excited state properties of organic and precious metal CT photocatalysts are strongly entangled. In contrast, redox potentials of polypyridine chromium(III) complexes, that feature purely metal‐centered SF states, are selectively tuned by incremental substituent effects of the CF3 group, while excited state energies and lifetimes remain ...

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

Chemistry – A European Journal, EarlyView.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

The One‐Step Synthesis of Biologically Active Isochromans from Lignin‐Derived Aromatic Monomers in Tunable Deep Eutectic Solvents

Chemistry – A European Journal, EarlyView.
A straightforward one‐step protocol enables the synthesis of bio‐based and biologically active isochromans through the Oxa‐Pictet cyclization involving diverse aldehydes, including vanillin in combination with lignin‐derivable homovanillyl alcohol, a prominent aromatic platform chemical obtainable via diol‐assisted fractionation of lignocellulose ...

Arene Incorporation and Ring Expansion in the Thermal Decomposition of a Divanadium(III) Complex With Four Bridging Methyl Groups

Chemistry – A European Journal, EarlyView.
Thermolysis of [{VCp*(µ‐CH3)2}2] (Cp* = η5‐C5Me5) in hexane leads to a tetranuclear cube‐type methylidene complex [{VCp*(µ3‐CH2)}4], while in benzenic solvents C6H5R produces the formal insertion of a CH fragment into the six‐membered aromatic ring of a solvent molecule to give trovacene derivatives with η7‐cycloheptatrienyl ligands [VCp*(η7‐C7H6R ...
