  Asymmetric epoxidation of styrenes catalyzed by molybdenum complexes with amino alcohol ligands

  摘要：

  Two common amino alcohols, prolinol and isolucinol, and their derivatives have been screened to coordinate with MoO2(acac)(2) to form in situ catalysts for asymmetric epoxidation of styrenes with the highest enantioselectivity of 84% for 4-fluoro-styrene under the optimized reaction conditions.

• Synthesis of CoMoO4 Nanofibers by Electrospinning as Efficient Electrocatalyst for Overall Water Splitting

  To improve the traditional energy production and consumption of resources, the acceleration of the development of a clean and green assembly line is highly important. Hydrogen is considered one of the most ideal options. The method of production of hydrogen through water splitting constitutes the most attractive research. We synthesized CoMoO4 nanofibers by electrospinning along with post-heat treatment at different temperatures. CoMoO4 nanofibers show a superior activity for hydrogen evolution reaction (HER) and only demand an overpotential of 80 mV to achieve a current density of 10 mA cm–2. In particular, the CoMoO4 catalyst also delivers excellent performances of oxygen evolution reaction (OER) in 1 M KOH, which is a more complicated process that needs extra energy to launch. The CoMoO4 nanofibers also showed a superior stability in multiple CV cycles and maintained a catalytic activity for up to 80 h through chronopotentiometry tests. This is attributed mainly to a synergistic interaction between the different metallic elements that caused the activity of CoMoO4 beyond single oxides. This approach proved that bimetallic oxides are promising for energy production.

  为了改善传统的能源生产和资源消耗，加快发展清洁和绿色的装配线非常重要。氢被认为是最理想的选择之一。通过分水制氢的方法是最具吸引力的研究。我们通过电纺丝和不同温度的后热处理合成了 CoMoO4 纳米纤维。 纳米纤维在氢进化反应（HER）中表现出卓越的活性，只需要 80 mV 的过电位就能达到 10 mA cm-2 的电流密度。特别是， 催化剂在 1 M KOH 中的氧进化反应（OER）中也表现出色，而氧进化反应是一个需要额外能量才能启动的复杂过程。 纳米纤维在多次 CV 循环中也表现出了卓越的稳定性，并在计时器测试中保持了长达 80 小时的催化活性。这主要归功于不同金属元素之间的协同作用，使 的活性超越了单一氧化物。这种方法证明，双金属氧化物在能源生产方面大有可为。
• Chiral molybdenum(VI) complexes with tridentate Schiff bases derived from S(+)-1-amino-2-propanol: Synthesis, characterization and catalytic activity in the oxidation of prochiral sulfides and olefins

  Seven chiral dioxidomolybdenum(VI) complexes with tridentate Schiff bases were synthesized by mono condensation of S(+)-1-amino-2-propanol with salicylaldehyde and its derivatives. One- (H-1, C-13) and two-dimensional (COSY, gHSQC and NOESY) NMR, IR, CD and UV-Vis spectroscopy were used for detailed characterization of the new molybdenum(VI) compounds. After optimization of the reaction conditions, the catalytic activities of these complexes were tested for the oxidation of olefins, i.e. styrene and cyclohexene, with aqueous 30% H2O2 or tert-butyl hydroperoxide (TBHP) as an oxidant. Moreover, the molybdenum(VI) Schiff base complexes were also able to catalyze the oxidation of prochiral sulfides [PhSR (R = Me, Bz)] to optically active sulfoxides in the presence of aqueous 30% H2O2.
