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.

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

Advanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...
