Article Abstract
The synthesis and organometallic chemistry of rhodium(I) complex [Rh(CNC-Me)(SOMe)][BAr ], featuring NHC-based pincer and labile dimethyl sulfoxide ligands, is reported. This complex reacts with biphenylene and chlorobenzene to afford products resulting from selective C-C and C-Cl bond activation, [Rh(CNC-Me)(2,2'-biphenyl)(OSMe)][BAr ] and [Rh(CNC-Me)(Ph)Cl(OSMe)][BAr ], respectively. A detailed DFT-based computational analysis indicates that C-H bond oxidative addition of these substrates is kinetically competitive, but in all cases endergonic: contrasting the large thermodynamic driving force calculated for insertion of the metal into the C-C and C-Cl bonds, respectively. Under equivalent conditions the substrates are not activated by the phosphine-based pincer complex [Rh(PNP-Pr)(SOMe)][BAr ].

This study investigated the impact of dietary zeolite supplementation on growth, cecal microbiota and digesta viscosity, digestive enzymes, carcass traits, blood constituents, and antioxidant parameters of broilers. A completely randomized design was used with 240 one-day-old broiler chicks randomly assigned to three dietary treatments (0%, 1.5%, and 3% zeolite as a feed additive) with four replicates of 20 chicks each.

Zeolite synthesis from fly ash offers recycling and environmental benefits for carbon dioxide capture, but varying fly ash composition from different sources has different compositions, leading to inconsistent adsorption results. To achieve high CO adsorption performance and stability in zeolite synthesis from fly ash systems, this study established an element-controlled simulated fly ash system with Ca/Fe gradient differences. Hydrothermal synthesis yielded zeolites with optimized oxide ratios for CO adsorption.

In this study, bovine peptide‑calcium chelates (BBP-Ca) were prepared via enzymatic hydrolysis to generate peptides and fermentation to obtain soluble calcium ions, which were then chelated together. The structural characteristics of BBP-Ca were comprehensively analyzed using FTIR, SEM, and UV spectroscopy. Additionally, its antioxidant capacity was evaluated by examining its protective effects against oxidative stress-induced damage in Caco-2 cells.

The -di(2-pyridyl)arenes, featuring a unique structure, hold significant promise for applications in fluorescent probes, synthetic nanoparticle stabilizers, and chemical synthesis. The mechanism of Ru-catalyzed decarboxylation and heteroarylation reactions of aryl carboxylic acids to access -dipyridylarenes was elucidated using DFT calculations, which involved C-H bond activation, oxidative addition, reductive elimination, and decarboxylation processes to form -di(2-pyridyl)arenes. The rate-determining step of the reaction is the second reductive elimination step with an energy barrier of 27.
