Alcohol‐Directed Carboamination of Conjugated Enynes
Angewandte Chemie, EarlyView.The first general three‐component intermolecular Pd‐catalyzed carboamination of conjugated enynes enables the coupling of anilines and aryl triflates to produce functionalized allenic amines, utilizing a native alcohol directing group to control regioselectivity.

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts
Advanced Materials, EarlyView.An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Synthesis of a Spirocyclic Oxetane-Fused Benzimidazole [PDF]
, 2015 A new synthesis of 2-oxa-7-azaspiro[3.5]nonane is described. Spirocyclic oxetanes, including 2-oxa-6-azaspiro[3.3]heptane were converted into o-cycloalkylaminoacetanilides for oxidative cyclizations using Oxone((R)) in formic acid.

Advanced Science, EarlyView.This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.
