1‐Azabicyclo[1.1.0]butanes (ABBs) on the Map: Mechanistic Pathways for Catalytic Ring Opening and Functionalizations

Angewandte Chemie, EarlyView.
Catalytic strain‐release ring opening and functionalizations of 1‐azabicyclo[1.1.0]butanes (ABBs) represent a promising strategy for accessing diverse azetidine products. These transformations proceed via polar pathways, radical pathways, and hybrid mechanisms that combine both.

Guiding Photochemical Process Intensification Through Kinetic Diagnostics

Angewandte Chemie, EarlyView.
Photochemical methodologies are typically optimized for yield, yet yield alone provides limited insight into scalability. We show that simple kinetic diagnostics identify the dominant process limitations and guide targeted engineering interventions.

Solvent‐Induced Structural Modulation in Nanoscale Covalent Organic Frameworks Enables High‐Performance NO2 Sensing

Angewandte Chemie, EarlyView.
Solvent intercalation disrupts the stacking order of protonated porphyrin‐based 2D COF nanoparticles, resulting in a less compactly packed structure with increased accessibility of porphyrin sites. This structural modulation leads to significantly enhanced chemiresistive NO2 sensing performance.

A de‐novo Approach Towards Divergent [3+2π/σ] Photocycloadditions of Nitrones via Assembly‐Controlled Kinetic Electron Transfer Gating

Angewandte Chemie, EarlyView.
A metal‐free photocatalytic platform converts nitrones into 4‐isoxazolines and oxa–aza–bicycloheptanes through divergent [3+2π/σ] cycloadditions. Assembly‐controlled kinetic electron transfer gating dictates substrate activation, enabling selective reactivity beyond thermodynamic expectations.
