Photooxygenation Reactions of Olefins Under Flow Conditions: An Experimental and In‐Silico Study
ChemPhotoChem, EarlyView.This study focuses on the setup and validation of the oxygenation reaction of alkenes to 1,2‐dioxetanes and hydroperoxides by a LED‐driven flow chemistry approach. An in‐silico a model was trained on reaction data that can tailor a specific chemical scope through fine‐tuning.

ChemSusChem, EarlyView.The synthesis of chemically recyclable polyhexahydrotriazine (PHT) aerogels, using N,N‐dimethyl lactamide, a nontoxic, label‐free solvent, is presented. The PHT aerogels exhibit low bulk density, high porosity, excellent thermal insulation, pronounced thermal stability, and enhanced mechanical performance. Furthermore, PHT aerogels can be depolymerized
