Summary: The doping of a Pd cluster with Ag atoms enhances the efficiency of Suzuki-Miyaura cross-coupling reactions by reducing the barriers for oxidation and reduction steps. The Ag atom adjacent to Pd sites in a Pd12Ag cluster donates charge to lower the barriers, demonstrating a unique donor-acceptor characteristic between Ag and Pd atoms. This study shows that altering the active site atom can control the activation energies of redox steps, suggesting the potential of silver-doped Pd-n clusters as catalysts.

Summary: Stereospecific Csp(3) Suzuki-Miyaura cross-coupling simplifies the synthesis of stereochemically complex small molecules, but current methods are not compatible with complex building blocks commonly found in natural products and other complex targets. This study presents a method for embedding the alpha-methyl-beta-hydroxyl motif within stereochemically defined secondary alkyl boronic ester building blocks, allowing for stereospecific cross-coupling. The use of beta-aryloxysilyl groups addresses the decrease in reactivity and side reactions associated with beta-oxygen-containing Csp(3) boronic esters. Mechanistic studies reveal the activation of a dihydroxysiloxaborolate as a transmetalation partner in a stereospecific process that retains configuration.

Summary: Zinc (Zn) and nitrogen (N) co-doped ZIF-8 derived hollow carbon (ZHC) is reported as a promising separator coating for lithium-sulfur batteries (LSBs) to control the shuttle effect. The presence of Zn and N in the nanohollow carbon structure helps mitigate polysulfide (PS) diffusion in LSBs, while the hollow interior of the carbon acts as a PS pocket to physically capture the PS. The ZHC shows promising performance with higher initial specific capacity and cycling stability compared to the parent ZIF-8.
