Summary: Two heteroleptic nickel oxothiolate complexes, [Ni(bpy)(mp)] (1) and [Ni(dmbpy)(mp)] (2), were synthesized and characterized, with complex 2 further characterized by single crystal X-ray diffraction data. The catalytic properties of both complexes for proton reduction were evaluated using different photosensitizers, leading to the discovery that complex 2 performs better in electrochemical experiments while complex 1 is more photocatalytically active. These results suggest that the HER mechanism follows different pathways in electrocatalysis and photocatalysis.

Summary: Formazan ligands have long been investigated as redox-noninnocent backbones, but their catalytic efficiency governed by redox noninnocence remains elusive. In this study, we report an iron-formazanate molecule that can efficiently prepare alpha-keto amides through a tightly regulated reductive cleavage of the substrate molecule by the electron donation from the formazanate, in a reversible manner.

Summary: A novel, high-efficient, safe, and reusable biochar adsorbent (Ni/Cu-BC) was synthesized and exhibited strong adsorption capacity for tetracycline according to the experiments. The study demonstrated that the bimetallic loading technique improved the adsorption strength of the adsorbent to tetracycline, and pi-pi interaction and complexation played a crucial role in the removal process. This study provides a new perspective on the design and environmental applications of biochar.

Summary: Catalytic systems using a small amount of organic photosensitizer and an inorganic (on-demand ligand-free) nickel(II) salt have been developed for cost-effective cross-coupling reactions. However, the formation of C(sp(2))-O bonds is still underdeveloped. This study presents a strategy for the synthesis of phenols using a nickel(II) salt and an organic photosensitizer, which was selected from an investigation into the catalytic activity of 60 different organic photosensitizers. Machine learning models incorporating descriptors derived from DFT calculations and RDKit were used to examine the impact of various parameters on the catalytic activity of photosensitizers, achieving a balance between precision and recall.

Summary: Planar chirality is an important form of molecular chirality that can induce enantioselectivity in transition metal catalysts. However, there are limitations in using late transition metal planar chiral complexes for enantioselective transformations due to synthetic constraints. Additionally, the methods for stereochemical assignment of planar chiral compounds are sometimes conflicting. This review aims to provide clarity on the assignment methods and overview the synthesis and use of late transition metal planar chiral complexes as enantioselective catalysts.

Summary: The study investigates the influence of binary ligand systems on the coordination modes of the Ni(II) metal center and resulting supramolecular architectures, demonstrating the formation of diverse coordination geometries in the presence of active polyamine ligands. The complexes exhibit interesting graph-set-motifs stabilized by various hydrogen bonds, and have been found to be highly active water reduction co-catalysts in a photo-catalytic hydrogen evolution process, with some complexes achieving high turnover numbers.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
