Summary: Mesoporous manganese doped cerium oxide catalysts prepared by inverse micelle method show superior activity in epoxidation of alkenes, with high conversion rate and selectivity. The high catalytic activity can be attributed to the specific fluorite crystal structure, high oxygen mobility, and the unique mechanism involving in situ generated reactive oxygen species.

Summary: In this study, vanadium-titanium doped MFI zeolite was synthesized and its synergistic catalytic effect in the epoxidation of 1-hexene and cyclohexene was investigated. The simultaneous incorporation of vanadium and titanium induced the partial charge transformation of titanium (IV) into titanium (III), leading to improved catalytic performance. Additionally, the dual insertion of vanadium and titanium increased the number of Lewis acid sites and external surface area, further enhancing the synergistic catalytic effect. The prepared VTS(0.15) zeolite exhibited high catalytic activity and good reusability.

Summary: Systematic investigations on the H atom transfer (HAT) thermodynamics of metal-O2 adducts are essential for designing transition metal catalysts for substrate oxidation and/or oxygenation directly using O2. Understanding the electronic structure features that govern the OO-H bond dissociation free energies (BDFEs) of metal-hydroperoxo species helps in quantitatively assessing the HAT activity of metal-superoxo complexes. This work calculated the BDFEs of two Co-III- and Mn-III-hydroperoxo complexes and tested the HAT capability of their superoxo congeners towards different substrates. The study emphasizes the role of both metal spin state and oxidation state in modulating BDFEs.

Summary: In this study, four different sidearm-containing Salen-Mn(III) complexes were synthesized and compared. It was found that the complex with a D-Boc-N-proline sidearm exhibited the best catalytic activity in the asymmetric epoxidation reaction. The steric hindrance and appropriate configuration of this sidearm facilitated the approach of olefins to the active center, resulting in improved reaction yields and enantioselectivities.

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.
