- Catalyst-free visible light-mediated selective oxidation of sulfides into sulfoxides under clean conditions
-
A facile and efficient visible-light-mediated method for directly converting sulfides into sulfoxides under clean conditions without using any photocatalysts is reported. This method exhibited favourable compatibility with functional groups and afforded a series of sulfoxides with high selectivity and yields. Moreover, in order to shed more light on such a transformation, detailed mechanism studies were carried out both experimentally and theoretically. The readily accessible, low-cost and eco-friendly nature of the developed method will endow it with attractive applications in chemical synthesis.

- Magneli-type tungsten oxide nanorods as catalysts for the selective oxidation of organic sulfides
-
Selective oxidation of thioethers is an important reaction to obtain sulfoxides as synthetic intermediates for applications in the chemical industry, medicinal chemistry and biology or the destruction of warfare agents. The reduced Magneli-type tungsten oxide WO3?xpossesses a unique oxidase-like activity which facilitates the oxidation of thioethers to the corresponding sulfoxides. More than 90% of the model system methylphenylsulfide could be converted to the sulfoxide with a selectivity of 98% at room temperature within 30 minutes, whereas oxidation to the corresponding sulfone was on a time scale of days. The concentration of the catalyst had a significant impact on the reaction rate. Reasonable catalytic effects were also observed for the selective oxidation of various organic sulfides with different substituents. The WO3?xnanocatalysts could be recycled at least 5 times without decrease in activity. We propose a metal oxide-catalyzed route based on the clean oxidant hydrogen peroxide. Compared to other molecular or enzyme catalysts the WO3?xsystem is a more robust redox-nanocatalyst, which is not susceptible to decomposition or denaturation under standard conditions. The unique oxidase-like activity of WO3?xcan be used for a wide range of applications in synthetic, environmental or medicinal chemistry.

- Alloxan-catalyzed biomimetic oxidations with hydrogen peroxide or molecular oxygen
-
Inspired by biological flavin catalysis, the nonionic alloxan derivatives were applied as the biomimetic catalysts for various oxidations, catalyzing oxidations of sulfides and amines with hydrogen peroxide or molecular oxygen under mild conditions with high yields in a short time. The whole catalytic cycle has been verified to be a biomimetic approach through the formation of the alloxan hydroperoxide reactive intermediate. Additionally, encouraging asymmetric catalytic results have been obtained with an easily prepared chiral alloxan in a sulfoxidation reaction.

- Highly efficient and selective photocatalytic oxidation of sulfide by a chromophore-catalyst dyad of ruthenium-based complexes
-
Electronic coupling across a bridging ligand between a chromophore and a catalyst center has an important influence on biological and synthetic photocatalytic processes. Structural and associated electronic modifications of ligands may improve the efficiency of photocatalytic transformations of organic substrates. Two ruthenium-based supramolecular assemblies based on a chromophore-catalyst dyad containing a Ru-aqua complex and its chloro form as the catalytic components were synthesized and structurally characterized, and their spectroscopic and electrochemical properties were investigated. Under visible light irradiation and in the presence of [Co(NH3)5Cl]Cl2 as a sacrificial electron acceptor, both complexes exhibited good photocatalytic activity toward oxidation of sulfide into the corresponding sulfoxide with high efficiency and >99% product selectivity in neutral aqueous solution. The Ru-aqua complex assembly was more efficient than the chloro complex. Isotopic labeling experiments using 18O-labeled water demonstrated the oxygen atom transfer from the water to the organic substrate, likely through the formation of an active intermediate, Ru(IV)=O.

- Selective oxidation of sulfides to sulfoxides using hydrogen peroxide over Au/CTN-silica catalyst
-
Chitosan (CTN) can be used as potential support to create environmentally friendly catalysts; however, chitosan's poor diffusion properties and low surface area limit its application. Direct deposition method on inorganic supports might be a feasible and simple solution, using core (silica nanosphere)-shell (chitosan) material as support, a series of Au/CTN-silica catalysts were prepared by inverse microemulsion system. These catalysts were active in catalyzing the oxidation of sulfides to sulfoxides with relative good conversion and high selectivity. This study confirms that the key factor governing catalytic performance of this catalyst should be the interaction between gold nanoparticles and N atoms.

- An Autocatalytic System of Photooxidation-Driven Substitution Reactions on a FeII4L6 Cage Framework
-
The functions of life are accomplished by systems exhibiting nonlinear kinetics: autocatalysis, in particular, is integral to the signal amplification that allows for biological information processing. Novel synthetic autocatalytic systems provide a foundation for the design of artificial chemical networks capable of carrying out complex functions. Here we report a set of FeII4L6 cages containing BODIPY chromophores having tuneable photosensitizing properties. Electron-rich anilines were observed to displace electron-deficient anilines at the dynamic-covalent imine bonds of these cages. When iodoaniline residues were incorporated, heavy-atom effects led to enhanced 1O2 production. The incorporation of (methylthio)aniline residues into a cage allowed for the design of an autocatalytic system: oxidation of the methylthio groups into sulfoxides make them electron-deficient and allows their displacement by iodoanilines, generating a better photocatalyst and accelerating the reaction.

- Poly(N-vinylpyrrolidone)-H2O2 and poly(4-vinylpyridine)-H2O2 complexes: Solid H 2O2 equivalents for selective oxidation of sulfides to sulfoxides and ketones to gem-dihydroperoxides

Complexes of poly(N-vinylpyrrolidone) (PVD) and poly(4-vinylpyridine) (PVP) with hydrogen peroxide have been prepared and their synthetic utility as solid H2O2 equivalents for the selective oxidation of sulfides to sulfoxides and ketones to gem-dihydroperoxides has been studied. These complexes are convenient and safe alternatives to H2O2 solutions and it is found that various symmetric as well as unsymmetrical sulfides undergo oxidation under mild conditions to provide the respective sulfoxides in high yields. A series of gem-dihydroperoxides were obtained from the corresponding ketones in good yields under ambient conditions. This journal is the Partner Organisations 2014.

- Palladium on carbon-catalyzed gentle and quantitative combustion of hydrogen at room temperature
-
A quantitative and gentle oxidation (combustion) of hydrogen in the presence of oxygen in a variety of solvents was achieved under palladium on carbon (Pd/C)-catalyzed conditions at ordinary pressures and temperatures. A quantitative generation of water accountable for the consumed oxygen was observed. While hydrogen peroxide (H2O2), which would form as an intermediate, was extremely unstable under the Pd/C-catalyzed conditions to be converted into water with accompanying oxygen generation, the stability of H2O2 was found to be increased in cold (0 °C) trifluoroacetic acid, and the formation of 64% H2O2 based on the consumed oxygen could be detected. A mechanistic elucidation study revealed that the single electron transfer and generation of the hydroxyl radical are involved in the gentle combustion process. The reactive oxygen species generated during the process was effectively utilized for the chemical oxidation of sulfides and phosphines to afford the corresponding sulfoxides and phosphine oxides, respectively.

Based on a previously discovered method for amine oxidations using flavins as catalysts and hydrogen peroxide as oxidant, a comparative kinetic study using NMR spectroscopy was undertaken with a series of flavins for amine and thioether oxidations. Included in this series is the newly prepared 7,8-difluoro-1,3-dimethyl-5-ethyl-5,10-dihydroalloxazine. This study shows that flavins, which bear electron-donating groups on the aromatic ring and/or the N-10 position, are less active and are deactivated during the course of the reaction. Moreover, flavins that are alkylated at the N-1 position instead of the N-10 position and having either no substituents or electron-withdrawing groups on the aromatic ring, remain the most active and stable.
