Influence of Substitution on the Interplay of Photochemical Switching and Phase Transitions in Azobenzene‐Based Molecular Materials

Angewandte Chemie, EarlyView.
This study investigates the influence of several substituents at different positions on photochemical and thermal properties of azobenzene‐based materials to provide valuable structure‐property relationships for the specific design of azobenzene‐based materials for future energy storage and phase change materials. ABSTRACT Understanding and translating

Cobalt‐Catalyzed [2σ+2π] Cycloaddition via Site‐Selective Capture of Bicyclobutane Diradical

Angewandte Chemie, EarlyView.
We report a Co(II)‐catalyzed strategy that combines thermal activation of bicyclo[1.1.0]butane (BCBs) with site‐selective radical capture to furnish head‐to‐head fused bicyclo[2.1.1]hexanes via [2σ+2π] cycloaddition with indoles. Detailed mechanistic studies (31P NMR, EPR, CV, and DFT) support the catalytic pathway, while phosphine‐oxide trapping and X‐
