Kang, Jun-Chen;Li, Zi-Hao;Chen, Chao;Dong, Li-Kun;Zhang, Shu-Yu research published �Paired Electrolysis Enabled Ni-Catalyzed Unconventional Cascade Reductive Thiolation Using Sulfinates� the research content is summarized as follows. Herein, authors have reported a nickel-catalyzed cascade reductive thiolation of aryl halides with sulfinates driven by paired electrolysis. This protocol uses sulfinates as the sulfur source, and various thioethers could be synthesized under mild conditions. By mechanism exploration, authors find that a cascade chem. step is allowed on the electrode interface and could alter the reaction pathway in paired electrolysis, whose findings could help the discovery of novel cascade reactions with unique reactivity.

A new, general approach to biheteroaryls: the Ni- and Pd-catalyzed multimetallic cross-Ullmann coupling of heteroaryl halides with triflates. An array of 5-membered, 6-membered and fused heteroaryl bromides and chlorides, as well as aryl triflates derived from heterocyclic phenols proved to be viable substrates in this reaction (62 examples, 63 ± 17% average yield). The generality of this approach to biheteroaryls were further demonstrated in 96-well plate format at 10μmol scale. An array of 96 possible products provided >90% hit rate under a single set of conditions. Further, low-yielding combinations was rapidly optimized with a single “Toolbox Plate” of ligands, additives and reductants.

In this work, the donor-acceptor (D-A) type conducting polymer with pendent nitrogen heterocycle (pyridine or pyrimidine) grafted polyterthiophene derivatives based electro-chem. sensor for paracetamol (PAR) was proposed. The structure of polymer materials was characterized by Fourier transform IR (FT-IR), UV-vis spectroscopy (UV-vis), X-ray diffraction (XRD), Energy dispersive spectroscopy (EDS), SEM (SEM), Thermogravimetric (TG) anal. methods. The electrochem. performance of polymer modified electrodes was investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods. The effect of pendent nitrogen heterocycles on the structure and electrochem. performance of polymers were studied. The results showed that the non-covalent interactions (hydrogen bonding and π-π stacking) between the polymers and PAR could improve the electrochem. behavior. Compared with that of pyridine, the pyrimidine grafted polymer exhibited better electrochem. performance with a min. detection concentration of 0.16 μM, a linear range of 0.16 μM-1300 μM, and a min. detection limit of 0.06 μM.

A new magnetic composite comprising starch, imidazolium and triazol groups was used as a support for stabilization of palladium nanoparticles. This material had been characterized by different techniques showing the presence of small and uniform Pd nanoparticles in about 2 nm size. Measuring contact angle confirmed important role of starch on increasing hydrophilic nature of the catalyst. Using 0.05 mol% of this catalyst aryl iodides or bromides reacted with boronic acids at room temperature in aqueous media and the corresponding products were obtained in very good to excellent yields. Hot filtration and PVPy poisoning tests confirmed the heterogeneous nature of the catalyst. E-factor of the catalyst was found in acceptable range and close to green chem. standards This catalyst was magnetically recovered and recycled for 10 consecutive times with small decrease in activity. Also, the robustness of this catalytic system was demonstrated by the characterization of the reused catalyst.

Gisbertz, Sebastian;Reischauer, Susanne;Pieber, Bartholomaeus research published 《 Overcoming limitations in dual photoredox/nickel-catalyzed C-N cross-couplings due to catalyst deactivation》, the research content is summarized as follows. Dual photoredox/nickel-catalyzed C-N cross-couplings suffer from low yields for electron-rich aryl halides. The formation of catalytically inactive nickel-black is responsible for this limitation and causes severe reproducibility issues. Here, that catalyst deactivation was avoided by using a carbon nitride photocatalyst were demonstrated. The broad absorption of the heterogeneous photocatalyst enabled wavelength-dependent control of the rate of reductive elimination to prevent nickel-black formation during the coupling of cyclic, secondary amines and aryl halides. A second approach, which was applicable to a broader set of electron-rich aryl halides, was to run the reactions at high concentrations to increase the rate of oxidative addition Less nucleophilic, primary amines was coupled with electron-rich aryl halides by stabilizing low-valent nickel intermediates with a suitable additive. The developed protocols enabled reproducible, selective C-N cross-couplings of electron-rich aryl bromides and also applied for electron-poor aryl chlorides.
