Chemistry – A European Journal, EarlyView.Easily synthesized [Ge([12]crown‐4)2][OTf]2 catalyzes the hydrosilylation of aldehydes to give reductively coupled ethers via a carbonyl‐activated reaction pathway. The mechanism proceeds through two distinct steps: hydrosilylation followed by etherification. The open coordination face of the active cationic Ge(II) catalyst facilitates the coordination

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

Non‐monotonic jet pinch‐off induced by droplet impact on immiscible liquids
Droplet, EarlyView.The graphical abstract shows the evolution of the central jet following droplet impact and summarizes the non‐monotonic dependence of the critical Weber number on the dimensionless film thickness and Ohnesorge number. Abstract Droplet impact on immiscible liquids can generate a central jet whose pinch‐off behavior plays a crucial role in many advanced ...
