Summary: A method for the isomerization of acyclic allylic alcohols into beta-functionalized ketones via 1,3-alkyl transposition is described. The reaction proceeds through light-driven proton-coupled electron transfer (PCET) activation and C-C beta-scission, leading to the formation of beta-functionalized ketone products. Insights from mechanistic studies have led to an improved reaction protocol for challenging substrates.

Summary: This review describes examples of carbon-carbon bond activation reactions at Mg, Al, and Zn. Different mechanisms for C-C bond activation at these metals, including α-alkyl elimination, β-alkyl elimination, oxidative addition, and electrocyclic reaction, have been proposed. Most reactions involve initial installation of the metal on a hydrocarbon scaffold followed by α-alkyl or β-alkyl elimination, rather than direct oxidative addition of C-C bonds. The emerging applications of Mg, Al, and Zn complexes as catalysts for C-C bond functionalization are also discussed.

Summary: Alkyl phosphates were used in liquid-liquid extraction of lanthanides and actinides, with TBP, TRIS, and BIS investigated for their extraction of Li, Na, K, Mg, and Ca ions. The selectivity for Li+ over Mg2+ was high in the binary system, with HNO3 concentration affecting extraction differently. In ternary and quinary systems, the metal ions may be extracted into water/ligand/NO3- aggregates in the organic layer.

Summary: Selective formation of dinuclear and heptanuclear metal cluster complexes were reported in this study, characterized using elemental analysis, infrared spectroscopy, and X-ray crystallography. Some complexes showed strong fluorescence properties, and were employed as catalysts in the cycloaddition reaction of CO2 to epoxide with moderate activities.

Summary: In this study, the effects of Zn-doping on the material structure and electrochemical properties of LiCoPO4 (LCP) were explored, revealing an unreported intermediate phase Li1/2Co1-nZnnPO4 and proposing two conjectured configurations. It was found that the redox potential and conductivity of Zn-doped LCP increase with doping concentration, leading to improved rate capability, cycle life, and energy efficiency.

Summary: This study investigated the behavior of a new type of ceramic biomaterial, bioresponsive ceramics, composed of a salt of calcium ions and phosphate esters. The findings revealed that these materials can transform into hydroxyapatite, a potential treatment for bone defects, in a specific body fluid. The size of the phosphate ester alkyl groups affected the transformation rate.

Summary: This study investigates the catalytic challenge posed by the substrate's phosphate ester to the enzyme MtnA. It explores the use of covalent catalysis via a phosphorylated residue to allow isomerization. However, the results suggest that phosphorylation is unrelated to catalysis. Unexpectedly, a second adduct was found in the C160S mutant, possibly due to proton transfer from C-2 to C-1 by Cys160.

Summary: This study reveals that the mechanism of MtnA enzyme catalyzing the conversion of MTR1P to MTRu1P may involve a proton transfer from C-2 to C-1. Phosphorylation is unrelated to catalysis but may be related to the formation of hemiketal adducts.

Summary: A facile method for the synthesis of substituted pyridines has been developed by NH4I-catalyzed cycloaddition of oxime acetates and alkyl pyruvate. The reaction proceeds through N-O bond cleavage and C-C bond formation, and shows mild conditions and high functional group compatibility.
