Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

European Journal of Organic Chemistry, EarlyView.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.

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

European 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

Catalytic Hydrogenation of Lignin‐Derived Aromatics With Rhodium Oxide in Water

European Journal of Organic Chemistry, EarlyView.
The easily available, easy‐to‐handle rhodium(III) oxide, Rh2O3, is shown to be a competent catalyst for arene hydrogenation, including chemoselective reduction of α,β‐unsaturated aryl ketones. Catalytic arene hydrogenation offers a direct pathway to saturated carbocycles. It can also be exploited to upgrade lignin‐derived aromatics.

Exercise‐specific plasma proteomic signatures in racehorses: Candidates for training adaptation and peak load monitoring

Equine Veterinary Journal, EarlyView.
Abstract Background Racehorses undergo profound physiological changes with training and competition, but current biomarkers inadequately capture the complex molecular dynamics of exercise. This study aimed to identify novel plasma biomarkers of training adaptation and peak load using high‐throughput proteomics.

Heteroatom location‐ and orientation mode‐dependent reverse intersystem crossing rate in multiple resonance emitters

FlexMat, EarlyView.
By constructing two pairs of isomers with different heteroatom anchoring positions, the relationship between heteroatom location and orientation mode and reverse intersystem crossing rate constant (kRISC) in multiple resonance (MR) emitters is systematically investigated.
