An Ambient Photocatalytic Approach to In‐Situ Prepare Cobalt/Cobalt Phosphide and Cobalt/Cobalt Phosphide@Graphene Heterojunction Nanomaterials With Optimized Charge Separation Effects for Highly Efficient Relayed Electrocatalytic NOX− Reduction to NH3

Carbon Energy, EarlyView.
A visible‐light‐driven ambient photocatalytic method in‐situ fabricates Co/CoP‐x and Co/CoP@rGO heterojunction with enhanced charge separation, enabling highly efficient relayed electrocatalytic NOx− reduction to NH3 with outstanding Faraday efficiency and ammonia productivity.

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
ABSTRACT The development of synthetic procedures for preparing metal nanoparticles with controlled size using sunlight opens new avenues toward more sustainable methods with lower energy consumption. Herein, we propose the use of double‐vacancy halide perovskites as precursors for engineering highly crystalline and small platinum nanoparticles (< 3 nm)

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

The Asymmetric Self‐Replicative Alkylation of N‐Arylaldimines Using Organolithium Reagents

Chemistry – A European Journal, EarlyView.
Here, we report a new asymmetric autoinductive reaction; the addition of nBuLi to N‐arylaldimines to form chiral lithium amides. The reaction proceeds with full conversion and complete transfer of chirality, representing the first example of an asymmetric autoinductive reaction with organolithium reagents.

Bioresponsive pseudoGlucosinolates (psGSLs) Release Isothiocyanates (ITCs) in the Presence of Nitroreductases

Chemistry – A European Journal, EarlyView.
This work introduces the concept of pseudoglucosinolates (psGSLs) and reports the synthesis and evaluation of nitroreductase‐responsive psGSLs. These compounds represent a complementary prodrug strategy to natural glucosinolates (GSLs) for the controlled release of isothiocyanates (ITCs), enabling bio‐responsive protein labeling, as demonstrated in ...
