Angewandte Chemie, EarlyView.This work reports a new metal–ester bonding strategy for anchoring molecular catalysts to metal oxide supports, achieving exceptionally high surface loadings. Catalyst reactivity is predictably tuned by the support's properties, enabling control over electronic behavior and reaction pathways, thus opening new possibilities for designing highly ...

Homoleptic and Heteroleptic Carbones L1‐C‐L2
Angewandte Chemie, EarlyView.DFT and CCSD(T) calculations reveal that heteroleptic carbones L₁–C–L2 are thermodynamically stable species even with a weakly binding donor such as N2. Bond strengths show no simple correlation with bond lengths. Weaker carbon‐ligand bonds in homoleptic complexes L1─C─L1 are mostly strengthened in heteroleptic carbons L1─C─L2, while stronger bonds L2 ...

Oxidative modification of proteins: An emerging mechanism of cell signaling
Frontiers in Physiology, 2012 There are a wide variety of reactive species which can affect cell function, including reactive oxygen, nitrogen, and lipid species. Some are formed endogenously through enzymatic or non-enzymatic pathways, and others are introduced through diet or ...

Kinetics and Reaction Mechanism of Biothiols Involved in SNAr Reactions: An Experimental Study
Frontiers in Chemistry, 2022 Few kinetic parameters, or reaction rates, are known up to date in detail about 1-chloro and 1-fluoro-2,4-dinitrobenzene (ClDNB and FDNB, respectively) with a series of biothiols in aqueous media. These biological nucleophiles with thiol groups have been

Multicyclic D‐Stereospecific Hydrolase Dimer With High Sustained Activity
Angewandte Chemie, EarlyView.Protein macrocyclization was applied to a thermally unstable D‐stereospecific hydrolase using in situ cyclization of proteins (INCYPRO). This site‐specific cross‐linking approach enhanced the resistance of the enzyme to heat and cosolvents.

Electrophile-Dependent Reactivity of Lithiated N-Benzylpyrene-1-Carboxamide
Molecules, 2022 In this paper, we describe the lithiation of N-benzylpyrene-1-carboxamide with RLi-TMEDA. We found that the reaction outcome strongly depends on the electrophile used in the quenching step.
