Author is Struwe, Julia; Korvorapun, Korkit; Zangarelli, Agnese; Ackermann, Lutz.

The ruthenium-catalyzed synthesis of diarylmethane compounds was realized under exceedingly mild photoredox conditions without the use of exogenous photocatalysts. The versatility and robustness of the ruthenium-catalyzed C-H benzylation was reflected by an ample scope, including multifold C-H functionalizations, as well as transformable pyrazoles, imidates and sensitive nucleosides. Mechanistic studies were indicative of a photoactive cyclometalated ruthenium complex, which also enabled versatile C-H allylations.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Hydrophobic POM Electrocatalyst Achieves Low Voltage “”Charge”” in Zn-Air Battery Coupled with Bisphenol A Degradation, published in 2021-06-16, which mentions a compound: 2208-59-5, Name is 2-(Pyridin-4-yl)-1H-benzo[d]imidazole, Molecular C12H9N3, Name: 2-(Pyridin-4-yl)-1H-benzo[d]imidazole.

Zn-air batteriesare a perspective power source for grid-storage. But, after they are discharged at1.1 to 1.2 V, large overpotential is required for their charging (usually 2.5 V). This is due to a sluggish oxygen evolution reaction (OER). Incorporating organic pollutants into the cathode electrolyte is a feasible strategy for lowering the required charging potential. In the discharge process, the related oxygen reduction reaction, hydrophobic electrocatalysts are more popular than hydrophilic ones. Here, a hydrophobic bifunctional polyoxometalate electrocatalyst is synthesized by precise structural design. It shows excellent activities in both bisphenol A degradation and oxygen reduction reactions. In bisphenol A containing electrolyte, to achieve 100 mA · cm-2, its potential is only 1.32 V, which is 0.34 V lower than oxygen evolution reaction. In the oxygen reduction reaction, this electrocatalyst follows the four-electron mechanism. In both bisphenol A degradation and oxygen reduction reactions, it shows excellent stability. With this electrocatalyst as cathode material and bisphenol A containing KOH as electrolyte, a Zn-air battery was assembled. When “”charged”” at 85 mA · cm-2, it only requires 1.98 V. Peak power d. of this Zn-air battery reaches 120.5 mW·cm-2. More importantly, in the “”charge”” process, bisphenol A is degraded, which achieves energy saving and pollutant removal simultaneously in one Zn-air battery.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 2208-59-5, is researched, SMILESS is C1(C2=CC=NC=C2)=NC3=CC=CC=C3N1, Molecular C12H9N3Journal, Journal of Physical Chemistry C called Interplay of Hydrophobic and Electrostatic Interactions in Modulation of Protonation-Deprotonation Equilibria of Two Positional Isomers in Their Complexes with Cucurbiturils, Author is Khorwal, Vijaykant; Nudurupati, Uma; Mondal, Sohidul Islam; Datta, Anindya, the main research direction is interplay hydrophobic electrostatic modulation; protonation deprotonation equilibrium positional isomer complex cucurbituril.SDS of cas: 2208-59-5.

Elucidation of host-guest chem. of 2-(4′-pyridyl)benzimidazole (4PBI) and 2-(2′-pyridyl)benzimidazole (2PBI) with cucurbiturils in aqueous solution is rather challenging. The guest mols. are capable of binding in three different states of protonation: cation C, tautomer T, and normal N. Charge distribution on the species governs the formation of the inclusion complexes. Binding modes of the guest mols. with cucurbiturils were investigated by proton NMR spectroscopy. 4PBI binds with its benzimidazole ring pointing inward, while the binding mode is opposite for 2PBI. This difference is governed by the position of substitution of the pyridyl ring. Energetics of complexation was studied by quantum chem. calculations for 4PBI-CB as 2PBI-CB type complexes, for each form (C, T, and N) of both the mols. Release of high energy water from cucurbituril cavity is the main driving force for complexation. Excited state proton transfer (ESPT) in 2PBI and 4PBI are affected strongly upon complexation, as is manifested in steady state and time-resolved fluorescence experiments
