Nickel-Mediated Dehydrogenative Aryl–Aryl Homocoupling of a Bulky Phosphino-Pyridine
, 2019 Aryl–aryl bond formation through dehydrogenative coupling is an attractive transformation due to the atom and step economy of working with unfunctionalized C–H bonds. Pd catalysts are most common for this process, but Ni complexes have also been targeted

3-Position-Selective C–H Trifluoromethylation of Pyridine Rings Based on Nucleophilic Activation
, 2022 The first example of the 3-position-selective C(sp2)–H trifluoromethylation of pyridine rings was established. 3-Position-selective trifluoromethylation was achieved by the nucleophilic activation of pyridine and quinoline derivatives through ...

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.

Pyridine-Triggered Fluorescent Switching in Coordination-Induced Allosteric Crystal Transformation
Two zinc complexes with stimuli-responsive properties have been realized in [Zn(L)2] (1) and [Zn(L)2(py)]·py (2) (HL = N-(2-hydroxybenzylideneamino)-1,8-naphthalimide, py = pyridine). The crystal-to-crystal transformation between 1 and 2 is achieved by

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing
Advanced Materials, EarlyView.Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.
