Iridium Complexes of a Triazole‐Derived Pincer Ligand: Synthesis, Reactivity, and Transfer Dehydrogenation Catalysis

open access: yesChemistry – A European Journal, EarlyView.
Ir pincer complexes bearing a triazole architecture in the pincer backbone and O‐ancillary chelating ligands are presented. These were employed in the catalytic transfer dehydrogenation of alkanes as well as of saturated heterocycles. Reactivity of these complexes with silver salts and Lewis acids produced various cationic iridium complexes.

Dual‐Functional Sulfonated Nanocellulose for Proton Exchange Membranes With High Proton Conductivity at Low Humidity

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable dual‐functional strategy yields simultaneously sulfonated and nanosized cellulose for proton exchange membranes with continuous hydrogen‐bond networks. These sustainable membranes exhibit low‐humidity proton conductivity twofold higher than Nafion 212, providing a robust solution for next‐generation fuel cells.

Dihydrogen Bond in the Aminoborane Complex of a Nicergoline Intermediate

open access: yesMolecules, 2019
An aminoborane side product from the nicergoline manufacture process was identified by single-crystal X-ray diffraction. As boranes of pharmaceutical molecules are quite rare, the binding potential of the BH3 group was investigated and compared with ...

Breaking the Temperature Barrier: Ultra‐Stable SiHfBCN Ceramic Coatings for High‐Temperature Pressure Sensing

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A 3D conductive net including HfC(N) conductive nanodomains and in‐situ carbon ribbons was generated within the amorphous SiHfBCN matrix by a new molecular‐level composition and microstructure design strategy, making a smooth and dense polymer‐derived SiHfBCN ceramic coatings exhibits excellent electrical conductivity, wide‐temperature sensing, cycling

Transfer Hydrogenation of Organic Azides to Amines by Ammonia Borane Complex Under Mild Conditions Catalyzed by Reusable Au Nanoparticles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Organic azides are readily reduced to amines under mild conditions by ammonia borane complex, catalyzed by a low loading level of reusable Au nanoparticles supported on TiO2. We present the first protocol for the chemoselective reduction of organic azides to amines by ammonia borane complex. In the presence of a low catalytic amount of Au nanoparticles
