Summary: This article introduces a Suzuki-Miyaura cross-coupling reaction of alpha-chloroacetates or alpha-chloroacetamides with arylboronic acids under visible-light irradiation, providing a mild method for the synthesis of alpha-arylacetates and alpha-arylacetamides. Additionally, the authors successfully synthesized a key intermediate of the plant hormone auxin, indole-3-acetic acid derivative, from 1-Boc-indole in two steps by combining an iridium-catalyzed C-H borylation and a palladium-catalyzed cross-coupling reaction.

Summary: This study presents a pioneering example of nickel-catalysed enantioconvergent Stille cross-coupling reactions. The reactions result in the formation of C-C bonds in good to high yields with excellent stereoselectivity, providing a practical and cost-effective method for synthesis. The innovative use of synergistic photoredox/nickel catalysis enables a novel single-electron transmetalation process, opening up new research possibilities in the field of Stille reactions.

Summary: In this study, the thermal kinetics and decomposition mechanism of the CL-20/BTF cocrystal explosive were investigated. It was found that the cocrystal does not undergo phase transition or solid-liquid melting before decomposition, and its thermal decomposition consists of two parallel autocatalytic paths.

Summary: Interest in unnatural alpha-amino acids has grown rapidly in recent years, and developing efficient methods for their enantioselective synthesis is a key objective. The use of a nickel-based chiral catalyst has enabled the enantioconvergent coupling of racemic alkyl electrophiles with alkylzinc reagents, yielding protected unnatural alpha-amino acids. This novel cross-coupling method has successfully produced enantioenriched unnatural alpha-amino acids for the synthesis of bioactive compounds.

Summary: This study provides a novel understanding of the thermal reaction behavior and mechanism of Ni/Al energetic structural materials in an inert atmosphere. The effect of Ni:Al molar ratios on their thermal reactions was discussed, and the thermal reaction was divided into two stages: the hard contact stage and soft contact stage. The results provide guidance for the practical application of Ni/Al energetic structural materials.

Summary: This paper reports the low-temperature synthesis of improved MgB2 particles with enhanced ignition and high energy release. The synthesis is achieved through a solid-state reaction, resulting in narrow-sized distribution and fine particle size. Surface analysis reveals the chemical states present on the synthesized particles. The synthesized MgB2 exhibits higher energy release compared to commercial powder, making it an attractive candidate for various energetic applications.
