A Two-Component Alkyne Metathesis Catalyst System with an Improved Substrate Scope and Functional Group Tolerance: Development and Applications to Natural Product Synthesis
Ill-defined but well-behaved: Although oligomeric in nature, alkyne metathesis catalysts formed in situ by mixing of a trisamido molybdenum alkylidyne complex and an appropriate trisilanol were found highly tolerant of sensitive functional groups and protic sites. This notion is witnessed by the total syntheses of the sesquiterpene lactone manshurolide, the immunosuppressive cyclodiyne ivorenolide A, as well as by studies toward the quinolizidine alkaloid lythrancepine I (see scheme).
Metal Ions Play an Essential Catalytic Role in the Mechanism of Ketol–Acid Reductoisomerase

Catalytically active Mg2+ ions in enzymes: Ketol–acid reductoisomerase is an enzyme of the branched-chain amino acid biosynthesis pathway. It has promise as a target for herbicides and antimicrobial agents, and as a catalyst for biofuel production. The enzyme requires specifically a dinuclear Mg2+ centre to activate a μ-hydroxide that initiates catalysis. In the presence of Co2+the substrate binds in a non-competent mode.
Alkali-Metal-Ion-Functionalized Graphene Oxide as a Superior Anode Material for Sodium-Ion Batteries
Fang Wan, Yu-Han Li, Dai-Huo Liu, Jin-Zhi Guo, Prof. Hai-Zhu Sun, Prof. Jing-Ping Zhang and Prof. Xing-Long Wu
Superior Na-storage properties of unreduced graphene oxide (GO) by a simple and scalable alkali-metal-ion (Li+, Na+, K+)-functionalized process has been achieved. Different alkali metal ions play different roles on adjusting the structure and Na-storage properties, and the GNa electrode exhibits much improved electrochemical properties in terms of higher rate performance and longer cycle stability compared to GO, GLi, and GK (see figure).
Mesoporous Trimetallic PtPdRu Spheres as Superior Electrocatalysts
Bo Jiang, Dr. Hamed Ataee-Esfahani, Dr. Cuiling Li, Prof. Saad M. Alshehri, Dr. Tansir Ahamad, Dr. Joel Henzie and Prof. Yusuke Yamauchi
Go electro! Mesoporous trimetallic PtPdRu spheres (see figure) with well-defined spherical morphology and uniformly sized pores were synthesized in an aq. solution using ascorbic acid as the reducing agent and triblock copolymer F127 as the pore directing agent. These mesoporous PtPdRu spheres exhibited enhanced electrocatalytic activity compared to commercial Pt black.
