Summary: The isolated three-coordinate germanone [IPrN](2)Ge=O has high thermal stability in arene solvents, but still reactive towards small molecules, mimicking nucleophilic transition-metal oxides. The O-atom transfer reaction proceeds via a [2+2] cycloaddition intermediate, as revealed by DFT calculations.

Summary: Interface Pt-O bonded Pt-Ov-BiOBr catalysts were designed for photocatalytic selective oxidation of 5-hydroxymethylfurfural (HMF). The Pt-O bond on the unsaturated coordination environment of Ov-BiOBr serves as an electron transport channel to efficiently generate O-2(-). Photogenerated h(+) gathers at the Pt-Ov-BiOBr interface to oxidize HMF to carbon-centered radicals. The spatial proximity of O-2(-) and carbon-centered radicals at the Pt-Ov-BiOBr interface promotes reciprocal collisions and reactions, enhancing the efficiency of HMF photocatalytic selective oxidation.

Summary: The photocatalytic N2 immobilization performance of NaNbO3 is enhanced via oxygen vacancy introduction and Pt loading. The Pt-loaded NaNbO3 with rich oxygen defects (Pt/O-NaNbO3) is synthesized by combining ion-exchange and photodeposition methods. The introduction of oxygen defects greatly affects the energy band structure, resulting in higher photoactivity and NH3 production rate compared to O-NaNbO3 and NaNbO3. The loaded Pt nanoparticles further increase surface charge separation, contributing to the increased photocatalytic activity.

Summary: The C-O bond is important due to its presence in biologically active molecules, pharmaceutical agents, and functional materials. Traditional methods involving strong base and acid have limitations, so the development of C-O bond-forming reactions using catalytic strategies is increasingly important. Copper-promoted radical-mediated C-O bond formation is gaining research interest due to advancements in free-radical chemistry and photoredox catalysis. This Perspective highlights and evaluates state-of-the-art techniques in this field, organized by reaction types and working models.

Summary: This review summarizes the research data on the reaction mechanisms of singlet oxygen with DNA, particularly with the guanine base, over the past four decades. The mechanisms of O-1(2) reaction with guanine and its oxidation product 8-oxo7,8-dihydroguanine are discussed at both the nucleoside level and when the base is inserted into DNA. Tentative mechanisms and hypotheses are proposed to explain conflicting and contradictory observations.

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.
