Luminescent probes were used for detecting various heavy metals and toxic compounds Novel sensor with excellent sensitivity and selectivity is highly demanding. Herein, the authors designed and synthesized a three-dimensional (3D) Cu-organic framework [[Cu₅(TMDP)₃Cl](ClO₄)₄]_n (1) [TMDP = 4,4′-di(4H-1,2,4-triazol-4-yl)methylbiphenyl] of pcu ¦Á-Po primitive cubic topol. with Schlafli symbol of {4.4.4.4.4.4.4.4.4.4.4.4.^*.^*.^*}. By taking advantage of metal clusters and triazole ligand as the MOF components, the newly obtained MOF is stable in various environments and can be potentially used as the sensor. Remarkably, this MOF-based sensor shows high sensitivity and selectivity toward Dy ion (Dy³⁺) in a multiple lanthanides mixed solution Besides, it exhibits luminescent quenching toward various cyano compounds This chiral cluster-based network provides a potential luminescent probe for various inorganic and organic compounds with high sensitivity and selectivity.

Wu, Ting-Feng published the artcileZirconium-redox-shuttled cross-electrophile coupling of aromatic and heteroaromatic halides, Recommanded Product: 4,4′-Dimethyldiphenyl, the publication is Chem (2021), 7(7), 1963-1974, database is CAplus and MEDLINE.

Herein, a homogeneous XEC method, which relied on a zirconaaziridine complex as a shuttle for dual palladium-catalyzed processes was reported. The zirconaaziridine-mediated palladium (ZAPd)-catalyzed reaction showed excellent compatibility with various functional groups and diverse heteroaromatic scaffolds. In accord with d. functional theory (DFT) calculations, a redox transmetallation between the oxidative addition product and the zirconaaziridine was proposed as the crucial elementary step. Thus, cross-coupling selectivity using a single transition metal catalyst was controlled by the relative rate of oxidative addition of Pd(0) into the aromatic halide. Overall, the concept of a combined reducing and transmetallating agent offered opportunities for the development of transition metal reductive coupling catalysis.

A catalytic system for a phosphorus ligand-free Suzuki-Miyaura reaction in water at room temperature was disclosed. Ammonium 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonate) (ABTS) was an efficient promoter and acted both as a ligand and as a surfactant for the synthesis of biaryl compounds via the Suzuki-Miyaura reaction in water. The targeted biaryl architectures were achieved under mild conditions with high efficiency and good functional group tolerance.

A reductive coupling reaction with indene, a non-heteroatom olefin used as a reducing agent. The scope of the substrate was wide. The homo-coupling, cross-coupling, and synthesis of 12 and 14-membered rings were realized. The control experiment, indene-product curve and d. functional theory calculations showed that the ¦Ç³-palladium indene intermediate was formed by C-H activation in the presence of cesium carbonate. The final product was obtained through a Pd (IV) intermediate or aryl ligand exchange. In addition, it was excluded the formation of palladium anion (Pd(0)^–) intermediates.

Tang, Hong published the artcileSynthesis of biaryl compounds via Suzuki homocoupling reactions catalyzed by metal organic frameworks encapsulated with palladium nanoparticles, Category: catalysis-chemistry, the publication is Inorganic Chemistry Communications (2021), 108368, database is CAplus.

Heterogeneous homocoupling reactions of phenylboronic acids were greatly accelerated via Suzuki homocoupling reactions. In this work, a tandem route was designed which firstly one part of phenylboronic acids reacted with iodine to form iodobenzenes, then another part of phenylboronic acids coupled with iodobenzenes to produce biaryl compounds The tandem reaction were catalyzed by a bifunctional heterogeneous catalyst of metal organic frameworks encapsulated with palladium nanoparticles (Pd@MOFs). This strategy for forming sym. C-C bond between benzene rings has obvious advantages such as high efficiency, easy separation, good recyclability and no addition of toxic halogenated benzene.

Construction of heterogeneous Pd/SiO₂ catalyst via the pollution-free strategy marked strong electrostatic adsorption has been reported for the application to Suzuki-Miyaura cross-coupling reactions. The exposed neg. charged oxygen groups, which were converted from the hydroxyl groups on the surface of silica under the alk. atm., could effectively anchor palladium species to form ultrafine Pd nanoparticles (Pd NPs) with an average particle size of 1.3 nm and high dispersion (43%). Pd/SiO₂ catalyst was endowed with the excellent catalytic performance which was that the yield of the Suzuki-Miyaura reaction between bromobenzene and phenylboronic acid at 40¡ãC was > 99% for 30 min and the TOF was ? 80,000 h^-1. The catalyst could be easily recovered and recycled by facile procedure without a significant decrease in catalytic activity, which was able to maintain the 90% yield after repeated for 8 times. In addition, a continuous flow reaction device was designed using the Pd/SiO₂ catalyst to effectively improve the production efficiency of biphenyl.

Jiang, Heyan published the artcileEfficient photocatalytic chemoselective and stereoselective C-C bond formation over AuPd@N-rich carbon nitride, Related Products of catalysis-chemistry, the publication is Catalysis Science & Technology (2021), 11(1), 219-229, database is CAplus.

Here, a AuPd@N-rich carbon nitride (NRCN) photocatalyst through simple ammonia solution heat treatment of carbon nitride and then AuPd NP loading was constructed. AuPd@NRCN exhibited extraordinary light color promoted catalytic performance in C-C bond formation under visible light in air. Surprisingly, both high chemoselectivity to unsym. Ullmann biaryl products RC₆H₄-C₆H₄R¹ (R = 3-chloro, 4-nitro, 2-methoxy, etc.; R¹ = H, 3-Me, 4-methoxy, etc.) and satisfactory stereoselectivity to Z-type Heck reaction products RC₆H₄CH=CHR² (R² = Ph, COOEt) could be achieved by changing the light source color. Various substrates exhibited great potential for the economical synthesis of unsym. biaryl products and Z-type olefins. Efficient visible light promoted C-I bond activation accompanied with improved photocatalytic coupling reaction efficiency over AuPd@NRCN was verified firstly by in situ DRIFTS. Considering that the Ullmann cross-coupling reaction is a multi-photon reaction, the improved photocatalytic performance in the Ullmann cross-coupling reaction using a combination of light sources with different colors might be due to the activation of different substrates and/or steps requiring different energies, and the combination of the two energy sources was beneficial for improving the activation efficiency of different substrates and/or steps. The activation of iodobenzene and styrene in the Heck reaction with light was also beneficial to the formation of the stilbene product. The light color promoted chemoselectivity and stereoselectivity are expected to have profound impact on organic synthetic methodol. improvement.

A new strategy for the direct cleavage of the C(sp³)-OH bond was developed via activation of free alcs. with neutral di-Ph boryl radical generated from sodium tetraphenylborate under mild visible light photoredox conditions. This strategy was verified by cross-electrophile coupling of free alcs. and carbon dioxide for the synthesis of carboxylic acids. Direct transformation of a range of primary, secondary, and tertiary benzyl alcs. to acids was achieved. Control experiments and computational studies indicate that activation of alcs. with neutral boryl radical undergoes homolysis of the C(sp³)-OH bond, generating alkyl radicals. After reducing the alkyl radical into carbon anion under photoredox conditions, the following carboxylation with CO₂ affords the coupling product.
