With the increasingly serious greenhouse effect, electrochemical carbon dioxide reduction reaction (CO2RR) has garnered widespread attention as it is capable of leveraging renewable energy to convert CO2 into value-added chemicals and fuels. However, performance CO2RR can hardly meet expectations because diverse intermediates complicated processes, necessitating exploitation highly efficient catalysts. In recent years, with advanced characterization technologies theoretical simulations, exploration catalytic mechanisms gradually deepened electronic structure catalysts their interactions intermediates, which serve a bridge facilitate deeper comprehension structure-performance relationships. Transition metal-based (TMCs), extensively applied in CO2RR, demonstrate substantial potential for further modulation, given abundance d electrons. Herein, we discuss representative feasible strategies modulate catalysts, including doping, vacancy, alloying, heterostructure, strain, phase engineering. These approaches profoundly alter inherent properties TMCs interaction thereby greatly affecting rate pathway CO2RR. It believed that rational design modulation fundamentally provide viable directions development toward conversion many other small molecules.

Four-coordinate organoboron derivatives present interesting chemical, physical, biological, electronical, and optical properties. Given the increasing demand for synthesis of smart functional materials based on chiral compounds, exploration stereoselective boron-stereogenic organo-derivatives is highly desirable. However, construction compounds stereogenic at boron has been far less studied than other elements main group due to configurational stability concerns. Nowadays, these species are no longer elusive configurationally stable have highlighted. The idea show potential building four-coordinate centre encourage future endeavors developments in field.

The diversified synthesis of chiral fluorinated cyclobutane derivatives has remained a difficult task in synthetic chemistry. Herein, we present an approach for asymmetric hydroboration and formal hydrodefluorination gem-difluorinated cyclobutenes through rhodium catalysis, providing α-boryl cyclobutanes monofluorinated with excellent regio- enantioselectivity, respectively. key to the success two transformations relies on efficient, mild highly selective rhodium-catalyzed HBPin (pinacolborane), which subsequent addition base, catalytic amount palladium some cases, results formation products four-membered ring retained. obtained are versatile building blocks that provide platform enantioenriched great diversity.

Transition metal-catalyzed alkene isomerization is an enabling technology used to install distal its original site. Due their well-defined structure, homogeneous catalysts can be fine-tuned optimize reactivity, stereoselectivity, and positional selectivity, but they often suffer from instability nonrecyclability. Heterogeneous are generally highly robust continue lack active-site specificity challenging rationally improve through structural modification. Known single-site heterogeneous for utilize precious metals bespoke, expensive, synthetically intense supports. Additionally, have mediocre inspiring us develop a catalyst with active site made readily available compounds of Earth-abundant elements. Previous work demonstrated that very formed upon protonation Ni[P(OEt)3]4 by H2SO4, generating [Ni–H]+ This incredibly active, also decomposes readily, which severely limits utility. Herein we show using solid acid (sulfated zirconia, SZO300), not only this decomposition prevented, high activity maintained, improved selectivity achieved, broader scope functional groups tolerated. Preliminary mechanistic experiments suggest the catalytic reaction likely goes intermolecular, two-electron pathway. A detailed kinetic study comparing state-of-the-art Ni Pd reveals highest seen Ni/SZO300 system. The reactivity Ni/SZO300, limited isomerization; it competent hydroalkenylation, hydroboration, hydrosilylation, demonstrating broad application catalyst.

With fluorinated pyridyl-substituted chiral biimidazoline ligand, this reaction enables straightforward access to wide variety synthetically valuable α-aryl from readily available starting materials. This features mild conditions, broad substrate generality, good functional group tolerance proceeds without using metal reductants or alkyl halides. Furthermore, alkenyl halides other electron-deficient alkenes such as acrylates phosphonates can be applied successfully. Preliminary mechanistic studies shed light on potential pathways roles organic amines.
