The N-N atropisomer, as an important and intriguing chiral system, was widely present in natural products, pharmaceutical lead compounds, advanced material skeletons. anisotropic structural characteristics caused by its special axial rotation have always been one of the challenges that chemists strive to overcome. Herein, we report efficient method for enantioselective synthesis axially frameworks via a cobalt-catalyzed atroposelective C-H activation/annulation process. reaction proceeds...
Herein, we disclosed an efficient synthesis of C–N axially chiral pyridine-N-oxides through cobalt-catalyzed enantioselective C–H activation and annulation under electro-oxidative conditions. This protocol is accomplished by using a readily available cobalt(II) catalyst salicyloxazoline (Salox) ligand in undivided cell. The combination electrochemical simple Co/Salox system enabled effective control over the chemo- enantioselectivity process. A broad range benzamides alkynes bearing diverse...
In silica supported iron Fischer–Tropsch catalysts, promotion with copper strongly enhances both hematite reduction and magnetite carbidisation, while potassium hinders of to but carbidisation in carbon monoxide.
Modification of active metals with metal oxide modifiers has attracted considerable attention in heterogeneous catalysis due to their synergistic effect. However, a controllable synthesis highly reactive and stable metal–metal hybrid nanocatalysts is difficult. To solve this problem, presynthesized IrM (M = Fe, Co, Ni) bimetallic nanoparticles were initially confined the mesopores SBA-15 then situ transformed Ir-MOx hybrids. The obtained Ir-MOx/SBA-15 show superior activity selectivity...
Abstract Organic doping has become an effective method to improve the performance of organic optoelectronic devices. However, understanding mechanism is limited by difficulty in obtaining highly ordered molecular packing structure. Herein, a new donor‐acceptor type triphenylamine‐acetylene‐based isoindigo derivative, (E)‐6,6′‐bis((4‐(diphenylamino)phenyl)ethynyl)‐[3,3′‐biindolinylidene]‐2,2′‐dione (BDPEBD), successfully designed and synthesized. The tetrahydrofuran solvent doped BDPEBD...
A series of NiP-x/Al2O3 catalysts containing different ratio metallic nickel to phosphides, prepared by varying Ni/P molar 4, 3, 2 through a co-impregnation method, were employed investigate the synergistic effect nickel-nickel phosphides in dry methane reforming reaction. The Ni/Al2O3 catalyst indicates good activity along with severe carbon deposition. presence phosphorus increases dispersion as well interaction between and alumina support, which results smaller particles. co-existence...
Herein we develop a new "cobalt(II)/organic oxidant" catalytic system for the selective activation of 1°, 2°, and 3° C(sp3)–H bonds to construct C–N C–O bonds, respectively. The method highlights use an organic compound (TsNHOPiv or its analogues) as emerging oxidant thus provides flexible strategy preparation indoline benzoxazine derivatives. Attractive advantages this cobalt catalysis include simple operation, low cost, mild conditions, broad substrate scope. Furthermore, catalytically...
Herein, the atroposelective construction of five-six heterobiaryl skeleton-based C-N chiral axis has been successfully accomplished via a Co-catalyzed C-H bond activation and annulation process, in which isonitrile was employed as C1 source 8-aminoquinoline moiety served both directing group integral part atropisomers, respectively. This conversion can be effectively carried out an environmentally friendly oxygen atmosphere, generating target axial heterobiaryls with excellent reactivities...
Shaped charge liner (SCL) has been extensively applied in oil recovery and defense industries. Achieving superior penetration capability through optimizing SCL structures presents a substantial challenge due to intricate rate-dependent processes involving detonation-driven collapse, high-speed jet stretching, penetration. This study introduces an innovative optimization strategy for that employs efficiency as the primary objective function. The combines experimentally validated finite...
Nanosized Ir catalysts suffer from serious side reactions and poor stability during hydrogenation of substituted nitroaromatics to produce aromatic amines. In this work, core-shell nanostructures with sub-4 nm Ir-CoOx hybrid cores mesoporous SiO2 shells were designed prepared overcome these problems. The converted IrCo alloy nanoparticles (NPs) inside through in situ calcination reduction pretreatments. Ir-CoOx@SiO2 nanoreactors prevented the agglomeration/sintering NPs, while allowing free...
Supported Rh nanoparticles (NPs) exhibit excellent activity for the chemoselective hydrogenation of halonitrobenzenes (HNBs), but their selectivity to aromatic amines is not satisfactory due side reaction on carbon–halogen bonds, and recycling stability limited aggregation leaching active component during long-term usage. Herein, we design a yolk–shell-structured catalyst that consists RhCu alloy cores hollow/microporous carbon shells (HCS) overcome these problems. The obtained RhCu@HCS with...
