C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

Chemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Synergistic extraction of critical metals from the oxalic leachate of spent FCC catalyst

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study introduces an improved hydrometallurgy process utilizing a synergistic approach to improve metal recovery from secondary sources of critical metals. It provides a more efficient alternative to traditional single‐extractant methods for separating critical metals from spent refinery catalysts.

Protic N‐Heterocyclic Carbene Ligands in Ruthenium‐Catalyzed Transfer Hydrogenation

Helvetica Chimica Acta, EarlyView.
The activity of ruthenium transfer hydrogenation catalysts is strongly influenced by the number of protic units in the N‐heterocyclic carbene ligand. Doubly protic NH, NH ligands induce slower activity than mono‐protic NH, NMe ligands, while NMe, NMe ligands display the highest activity, suggesting metal‐ligand cooperativity is not beneficial for these
