Abstract Compared to the most popular directing‐group‐assisted strategy, “undirected” strategy for C−H bond functionalization represents a more flexible but challenging approach. Reported herein is gold‐catalyzed highly site‐selective C(sp 2 )−H alkylation of unactivated arenes with 2,2,2‐trifluoroethyl α‐aryl‐α‐diazoesters. This protocol demonstrates that high can be achieved without assistance directing group. In this transformation, both gold catalyst and trifluoroethyl group on ester...
Abstract Hydrogen generation via electrochemical splitting plays an important role to achieve hydrogen economy. However, the large‐scale application is highly limited by high cost and low efficiency. Herein, a new type of rechargeable Zn–hydrazine (Zn–Hz) battery proposed realized bifunctional electrocatalyst based on two separate cathodic reactions evolution (discharge: 2H 2 O + e − → H 2OH ) hydrazine oxidation (charge: ). This Zn–Hz battery, driven temporally decoupled cathode during...
Abstract Chiral dihydrobenzofuran units are frequently present in molecules with significant biological and pharmaceutical activities. Herein, we the first enantioselective formal [4+1] annulation of Morita‐Baylis‐Hillman carbonates o ‐quinone methides ( ‐QMs) catalyzed by a newly designed chiral phosphine catalyst. Under mild eco‐friendly conditions, wide range polysubstituted dihydrobenzofurans were obtained good yields excellent enantioselectivities. magnified image
Here, a catalyst-controlled chemodivergent 1,6-addition of p-quinone methides with alkynes was developed, affording diverse alkynyl- and vinyl-substituted diarymethanes. In this transformation, copper catalyzed the direct p-QMs alkynes, while iron promoted three components reaction p-QMs, halogens from salts or added HX acid. The salient features transformation include completely controllable chemoselectivity, mild conditions, inexpensive catalysts, good substrates scopes.

A three-dimensional metal-covalent organic framework (3D-MCOF) based on cyclic trinuclear units was synthesized using tetrahedral linkers and copper-based complexes. The novel type of 3D-MCOF, named 3D-CTU-MCOF, with the ctn topology, is reported herein for first time. Our study demonstrated enhanced electrocatalytic capacity CO2 reduction reaction 3D-CTU-MCOF compared to independent units.
Abstract Herein, a Brønsted acid‐catalyzed C( sp 2 )−H functionalization of free phenols with 1,3‐dienes has been developed. In this transformation, triflic acid promoted C−H bond under mild conditions in site‐selective manner. magnified image
ZnO phosphor was synthesized by annealing powder at low O2 partial pressure and in vacuum. has two emissions, which are located about 380 nm (UV emission) 510 (green emission). The UV emission can be attributed to the exciton emission, is a single-center process, whereas green related native defects, such as V•O V′Zn, two-center (donor-acceptor) recombination process. high-density excitation favors likely appears samples annealed pressure. It shown that energy transfer may occur from center...
