Photoredox‐Catalyzed Hydroalkylation of C(sp3)–H Acids

open access: yesChemistry – A European Journal, EarlyView.
Two versatile photoredox catalysis platforms were developed to engage C(sp3)–H acids in hydroalkylations, cross‐couplings, and oxidative cyclizations. Extensive synthetic and mechanistic investigations demonstrate a complementarity between the activation mechanisms of these two systems.

Removal of benzotriazoles from domestic wastewater using Pleurotus ostreatus fungal pellets

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Removal of benzotriazoles from domestic wastewater using a fungal pellet reactor with Pleurotus ostreatus. The system effectively removed CBTR (70%), while BTR (19%), 5‐TTR (17%), and OH‐BTH (16%) showed moderate removal. Abstract Benzotriazoles are a group of persistent and mobile substances commonly found in aquatic environments due to inefficient ...

Visible‐light‐switchable azobenzenes: Molecular design, supramolecular systems, and applications

open access: yesNatural Sciences, Volume 3, Issue 1, January 2023., 2023
Abstract Photocontrol of functional molecules and supramolecular systems provides promising directions for the development of innovative materials and technologies. Reversible photoswitches that can isomerize among different states play a vital role in such photoresponsive systems. However, the commonly used UV light for triggering the isomerization of

Real‐Time In Situ Raman Monitoring of Photomechanochemical Reactions

open access: yesChemistry–Methods, EarlyView.
A proof‐of‐principle setup for real‐time in situ monitoring photomechanochemical reactions is presented, using photoisomerization of azobenzenes, and photolysis of adamantane diazirine, as model reactions. With 4‐methoxyazobenzene it is also shown that multiple photoisomerization cycles can be performed and monitored in a ball mill, while with ...

Molecular Fragmentation as a Strategy to Access Hyperpolarised Compounds from Para‐Hydrogen

open access: yesChemPhysChem, Accepted Article.
Hyperpolarisation significantly increases the detectability of molecules in magnetic resonance spectroscopy and imaging. Beyond recent advancements in hardware and catalyst design, this article discusses harnessing the inherent chemical reactivity of hyperpolarisation target molecules as a strategy to expand the scope and versatility of para‐hydrogen ...
