Abstract The sluggish oxygen evolution reaction (OER) is a pivotal process for renewable energy technologies, such as water splitting. discovery of efficient, durable, and earth‐abundant electrocatalysts oxidation highly desirable. Here, novel trimetallic nitride compound grown on nickel foam (CoVFeN @ NF) demonstrated, which an ultra‐highly active OER electrocatalyst that outperforms the benchmark catalyst, RuO 2 , most state‐of‐the‐art 3D transition metals their compounds. CoVFeN NF...
Abstract Hydrogen evolution reaction (HER) is a key step for electrochemical energy conversion and storage. Developing well defined nanostructures as noble‐metal‐free electrocatalysts HER promising the application of hydrogen technology. Herein, it reported that 3D porous hierarchical CoNiP/Co x P multi‐phase heterostructure on Ni foam via an electrodeposition method followed by phosphorization exhibits ultra‐highly catalytic activity HER. The optimized achieves excellent performance with...
Abstract Electrolysis of water, especially alkaline water electrolysis (AWE), is the most promising technology to produce hydrogen in industry. However, only 4% total produced this way because electrode materials are expensive, inefficient, or unstable. Here, it reported that large‐scale 3D printed martensitic steel (AerMet100) can be bifunctional for AWE with high catalytic performance, which may dramatically increase green‐hydrogen percentage market and provide strategic planning energy...
Abstract A highly efficient asymmetric cascade reaction between alkynyl esters and allylic alcohols has been realized. Key to success was the combination of a hydroalkoxylation catalyzed by π‐acidic gold(I) complex with Claisen rearrangement chiral Lewis acidic N,N′‐dioxide–nickel(II) complex. range acyclic α‐allyl β‐keto were synthesized in high yields (up 99 %) good diastereoselectivities 97:3) excellent enantioselectivities % ee ) under mild conditions. These products can be easily...
Organic azides play important roles in synthetic chemistry, chemical biology, drug discovery, and material science. Azido-functionalization of alkenes is one the most efficient procedures for rapid introduction azide group into organic compounds. But only a few examples have been documented catalytic asymmetric version azidation alkenes. Herein, we report an unprecedented highly diastereo- enantioselective bromoazidation α,β-unsaturated ketones catalyzed by chiral N,N′-dioxide/Fe(OTf)2...
A series of chiral β-lactam bridged analogues (3-substituted 1,4-diaryl-2-azetidinones) combretastatin A-4 (CA-4) were synthesized asymmetrically, and their antitumor activities evaluated in vitro vivo. The cocrystal structure tubulin complex with compound 9 was determined by X-ray crystallography, which showed that binds to the same site as colchicine similar binding mode, absolute configuration its C-4 first identified demonstrated be critically important for antiproliferative activities.
The first iron(III)/N,N'-dioxide-catalyzed asymmetric haloamination of 3-alkylidene- and 3-arylidene-indolin-2-ones was developed, affording the corresponding chiral oxindole derivatives bearing vicinal haloamine substituents with excellent results (up to 99% yield, ee, >19 : 1 dr). This iron catalyst also exhibits perfect enantioselectivity for chalcone derivatives. cooperative activation substrate reagent in concert guarantees high stereoselectivity.

Halofunctionalization methods enable the vicinal difunctionalization of alkenes with heteroatom nucleophiles and halogen moieties. As a fundamental transformation in organic synthesis, catalytic asymmetric variants have only recently been reported. In sharp contrast to halocyclization simple which involves nucleophile-assisted alkene activation process, halofunctionalization enones developed by our laboratory features an electrophile-assisted 1,4-addition pathway. Our work this area has...
We report the enantioselective formation of quaternary stereogenic centers by intermolecular addition malononitrile, an acyl anion equivalent, and related pronucleophiles to several 1,3-disubstituted acyclic 1,3-dienes in presence a Pd–PHOX catalyst. Products are obtained up 88% yield 99:1 er most cases formed as single regioisomer. The products' malononitrile unit undergoes oxidative functionalization afford β,γ-unsaturated carbonyls bearing internal olefins α-quaternary centers.
In this work, we employed an asymmetric auxiliary organic ligand (1,1,1-trifluoroacetylacetone, Htfac) to further regulate the magnetic relaxation behavior of series Dy2 single-molecule magnets (SMMs) with a N1,N3-bis(3-methoxysalicylidene)diethylenetriamine (H2L) ligand. Fortunately, air-stable complex, [Dy2(L)2(tfac)2] (1; Htfac = 1,1,1-trifluoroacetylacetone) was obtained at room temperature. A structural analysis indicated that some Dy-O or Dy-N bond lengths for 1 are not in range those...
