Ambient Hydrocarbonylation of Olefins Enabled by Visible‐Light

open access: yesAdvanced Science, EarlyView.
A novel photo‐induced methodology for hydrocarbonylation has been established, resolving the inherent conflicts between competitive olefin and CO insertion in traditional methods that necessitate harsh conditions. Accordingly, an efficient and versatile hydrocarbonylation of olefins enabled by visible‐light irradiation under ambient conditions has been

Enantioselective Determination of Chiral Fungicides in Food Samples Using Automated Dispersive Microextraction Coupled With UHPLC–MS/MS

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
The use of fatty acids and bio‐derived solvents eliminates the need for toxic solvents and, when combined with automated workstations, enables parallel sample processing, thereby improving extraction efficiency and reducing human error. ABSTRACT An enantioselective analytical method based on automated dispersive liquid–liquid microextraction (DLLME ...
