Electrocatalytic Dehydrogenative Lactonization of Benzylic Alcohols: A Sustainable Access to Phthalides via N‐hydroxyphthalimide Mediation

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A mild, scalable electrocatalytic method for direct lactonization of benzylic alcohols to phthalides using N‐hydroxyphthalimide as a redox mediator is reported. This metal‐free process proceeds via a phthalimide‐N‐oxyl‐mediated hydrogen atom transfer mechanism, shows broad scope with good to excellent yields, and enables late‐stage functionalizations ...

Cu(I)‐Catalyzed Interrupted Cycloaddition Between Azides, Ag(I)‐Acetylides, and Diorganoyl Dichalcogenides

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Unleashing the power of Ag(I)‐acetylides with LiCl/dimethyl sulfoxide (DMSO). The LiCl/DMSO mixture have an unexplored ability to dramatically increase the solubility of Ag(I)‐acetylides regardless of their molecular structure, which is explored to achieve high chemoselectivity in the Cu(I)‐catalyzed interrupted cycloaddition between organic azides, Ag(

Acidogenesis‐Propelled Coordination Transition in Light‐Triggered Fe‐Polyphenol Polymer for Reactive Oxygen Species‐Augmented Antitumor Therapy

open access: yesAdvanced Science, EarlyView.
A novel iron‐polyphenol‐photoacid coordination polymer (FeBPs) is designed to achieve red light‐triggered external acidification and internal coordination regulation, where this light‐controlled acidification induces coordination changes that enhance Fe active site exposure and provide H+ for beneficial Fe3+/Fe2+ conversion, thereby accelerating ROS ...
