Origin of Room Temperature Methanol Synthesis over Hcp‐PdMo

Angewandte Chemie International Edition, EarlyView.
The hexagonal close‐packed PdMo (hcp‐PdMo) intermetallic catalyst exhibits the room temperature catalytic activity for CO2 hydrogenation to methanol, where the adjacently arranged Pd and Mo sites play important roles in methanol synthesis. Mechanism study revealed that the reaction proceeds via a reverse water‐gas shift and subsequent CO hydrogenation (

Integrated Chemoenzymatic Synthesis of the mRNA Vaccine Building Block N1‐Methylpseudouridine Triphosphate

Angewandte Chemie International Edition, Accepted Article.
Pseudouridine‐5’‐triphosphate (ΨTP) and the N1‐methylated derivative (m1ΨTP) are critical monomer building blocks of the currently used mRNA vaccines, yet efficient methods of their synthesis from readily accessible substrates remain underdeveloped. We herein report notably atom‐economic and high‐yielding biocatalytic route toward ΨTP (83% yield) and ...

High‐Pressure Synthesis of Nitrogen‐rich Y(N5)3·N2 Pentazolate with Perovskite Topology

Angewandte Chemie International Edition, Accepted Article.
The discovery and stabilization of the cyclo‐N5⁻ anion have introduced a class of pentazolate compounds with significant potential as high‐energy‐density materials. This potential could be further enhanced by increasing the pentazolate‐to‐metal ratio. Here, we report the high‐pressure high‐temperature synthesis and characterization of a novel yttrium ...

Reactivity of Pnictaalumenes towards 1,3‐Dipole Molecules

Angewandte Chemie International Edition, Accepted Article.
Alkynes undergo 1,3‐dipolar cyclisation reactions with organic azides giving 1,2,3‐triazoles. Pnictaalumenes RPn=AlRˈ are the isoelectronic congeners of alkynes, hence a similar reactivity towards 1,3‐dipole molecules is expected. Herein, we report the reactions of DippTerPn=AlCp* (DippTer = 2,6‑(2,6‐iPr2C6H3)‐C6H3, Cp* = [Me5C5]−, Pn = P, As) towards ...

Identification of Ti(salen)‐Complexes for Efficient Catalysis in Single Electron Steps by Cyclic Voltammetry (CV)

Angewandte Chemie International Edition, Accepted Article.
We describe the identification of an active Ti(salen)‐catalyst for the radical arylation of epoxides by a CV study of mechanism‐based predictors, such as the redox potentials of the complexes and their EqCr‐equilibria, for the success of catalysis. Surprisingly, the by far most active catalyst features an uncommon tetrasubstituted ligand backbone that ...

MOF Coating Enhances the Ion Tolerance of Micromotors

Angewandte Chemie International Edition, EarlyView.
This work reported a novel method to significantly enhance the ion tolerance of EMNMs using a MOF coating via controllable heteroepitaxial growth, enabling effective motion in high‐salt environments and propulsion through biological tissues under 980 nm NIR light, with potential applications in targeted drug delivery.
