Copper‐Catalyzed Three‐Component Selective 1,4‐Amino Oxygenation of 1,3‐Dienes

Angewandte Chemie, EarlyView.
Enclosed is a copper‐catalyzed selective 1,4‐amino oxgenation of 1,3‐dienes with the presence of a strong Brønsted acid. This three‐component transformation offers a novel and powerful approach to construct (E)‐1,4‐allylic amino oxygenated motifs by the simultaneous installation of structurally diverse alkylamines and alcohols directly onto 1,3‐dienes.

Probing Ultrafast Dynamics with Time-resolved Multi-dimensional Coincidence Imaging: Butadiene

, 2013
Time-resolved coincidence imaging of photoelectrons and photoions represents the most complete experimental measurement of ultrafast excited state dynamics, a multi-dimensional measurement for a multi-dimensional problem. Here we present the experimental

Comparative Insights and Overlooked Factors of Interphase Chemistry in Alkali Metal‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review presents a comparative analysis of Li‐, Na‐, and K‐ion batteries, focusing on the critical role of electrode–electrolyte interphases. It especially highlights overlooked aspects such as SEI/CEI misconceptions, binder effects, and self‐discharge relevance, emphasizing the limitations of current understanding and offering strategies for ...

Double E─H Bond Activation of Ammonia and Water by Cyclic Gallaphosphene L(OCP)GaPGaL

Angewandte Chemie, EarlyView.
Cyclic gallaphosphene 1 undergoes a twofold E─H bond activation with ammonia and water via a beneficial interplay between the polar “GaPGa” unit and the electrophilic nature of the C center in the bridging PCO unit, yielding six‐membered heterocycles 2 and 3, in which both nucleophilic phosphorus atoms are protonated.
