Summary: Transition metals, with palladium being the preferred catalyst, play a crucial role in modern catalysis. Carbonylative Suzuki-Miyaura coupling reaction stands out as an attractive method for the direct incorporation of a CO fragment to prepare biaryl or aryl/alkyl ketones. This method is not only valuable for the synthesis of ketones, which are important building blocks with pharmaceutical and agrochemical applications, but also for the direct joining of molecular fragments via a CO bridge to synthesize various natural bioactive molecules.

Summary: Highly regiospecific azide-alkyne cycloaddition (AAC) reactions have been achieved under mechanochemical conditions. Cu beads were used for efficient synthesis of complex compounds without generating unwanted byproducts. High-speed ball milling strategy was applied for the synthesis of pharmaceutical agents and structural confirmation.

Summary: In this study, a layered carbon dot composite catalyst (NiFe LDH@CDs) was prepared using a one-step coprecipitation method, without the need for heating or hydrothermal treatment. The CD-functionalized catalyst facilitated rapid charge transfer and accelerated the oxygen evolution reaction. Additionally, the heterojunction structure formed between NiFe LDH and CDs efficiently suppressed photoelectron-hole recombination.

Summary: We designed and synthesized a NN-CoII bidentate complex and used it for the amination of alcohols under mild and solventless conditions. The complex exhibited good reactivity towards both primary and sterically hindered secondary alcohols, providing high yields of amines. The pyrazole moiety in the ligand played a crucial role in the reaction. Furthermore, we demonstrated the reusability of the complex as a homogeneous cobalt catalyst.

Summary: Replicating the enzymatic surface microenvironment in vitro is challenging, but constructing an analogous model could facilitate our understanding of surface effects and aid in developing an efficient bioinspired catalytic system. In this study, five unique Cu2O morphologies were generated, and the surface morphology variations were found to be a consequence of differences in the exposure of low-index facets. The reactivity of Cu2O was found to be influenced by the proportion of {110} planes, with r-Cu2O exhibiting the highest reactivity.

Summary: Defect engineering has been shown to improve the photocatalytic performance. This study investigated the use of defect-rich UiO-66-NH2 wrapped by ZnIn2S4 as a catalyst for photocatalytic H2O2 production. The defects in UiO-66-NH2 enhanced O-2 adsorption and charge separation, leading to higher H2O2 yield. The insights from this work can advance the research in defect engineering of MOFs and photocatalytic H2O2 synthesis.

Summary: This review presents the recent research advances on single-atom catalysis for deep reduction of CO2. Detailed introductions and summaries were classified into three categories based on proton-coupled multi-electron transfer approaches: strengthening metal-support interaction, rational design and regulation of coordination environment, and development of SACs with multi-atom active sites. The challenges and future research directions in the field of SACs for CO2 reduction are also proposed.

Summary: This article reports a transition-metal-free process for in situ denitrogenation of tosylhydrazones, resulting in the production of various sulfones. The authors used a phenalenyl-based odd alternant hydrocarbon as a photoredox catalyst, which acted as a potent oxidant to facilitate the denitrogenation reaction. The method showed wide functional-group tolerance and high yields, making it suitable for late-stage modification of natural products.

Summary: Currently, the production of acetic acid through the carbonylation reaction of methanol has limitations, leading to the exploration of alternative methods using heterogeneous catalysts. This study investigates the methanol carbonylation reaction over a Cu-H-MOR catalyst and proposes a reaction mechanism based on the catalytic behavior and performance of the catalyst. The results provide insights into the reaction mechanism and the involvement of acid and redox centers.
