Oxidative N-dealkylation of tertiary amines with tetraethyl ammonium periodate led to formation of corresponding N-dealkylated and mono-oxygenated products. One electron transfer dominates over hydrogen abstraction in the reaction mechanism.

Novel restricted access media–molecularly imprinted magnetic microspheres that displayed water-compatibility, exclusion of biomacromolecules, and selective enrichment of analytes were prepared by a one-pot surface imprinting method for the magnetic dispersion microextraction of trace fluoroquinolones from egg samples.

Poly(γ-4-methylbenzyl-L-glutamate) pyridinium tetrafluoroborate conjugates with constant main chain length, various pyridinium pendants, and high grafting efficiency can be readily prepared by nucleophilic substitution and ion-exchange reaction. They can exhibit reversible UCST-type phase behaviours in both methanol and water depending on the type of pyridinium pendants.

This paper investigates the use of (10,10) armchair carbon nanotube (CNT(10,10)) as a new drug delivery system for 1,4-dihydropyridine derivatives.

Novel strontium oxide/calcium oxide (SrO-CaO) mixed metal oxides heterogeneous catalyst is synthesized to highlight its catalytic potential for the transformation of Jatropha oil to green biofuels via an ultrasonic-assisted transesterification process.

The construction of the first Salen-type 3D lanthanide complex using Salen ligands and mixed lanthanide counter-ions is described.

CoWO₄/g-C₃N₄ was synthesized by precipitation and calcination, and used as a catalyst for oxidative desulfurization. In the process, CoWO₄/g-C₃N₄ showed excellent desulfurization activity and the desulfurization rate reached 92.9 %. Moreover, the catalyst could be recycled at least five times without any clear decrease in catalytic activity.

A polyglycidyl methacrylate electrospun scaffold was fabricated encapsulating a lipophilic drug, PXS64. Efficacy of the developed scaffold was explored for skin scar therapy applications.

Three zinc phosphites have been synthesized and characterized. Their frameworks are constructed from 4-connected ZnO₄ tetrahedra and 3-connected HPO₃ pseudopyramids. There are 12-membered ring (12-MR) and 8-MR apertures in their (3,4)-connected network. Helical chains are observed in compound 3.

Effect of imidazolium cation (MIM⁺) on the electroreduction of CO₂ to CO was investigated by linear sweep voltammetry (LSV), cyclic voltammetry (CV), constant potential electrolysis (CPE), and density functional theory (DFT) computations. It is interesting to find that the catalytic effect of MIM⁺ is sensitive to the alkyl chain length on its N1-position.

Various glycosylation reactions were tried in an effort to synthesise β-linked tutin glycosides, found in toxic honeys. Cationic palladium-mediated glycosylation gave the α-linked tutin tetrabenzyl glucoside (5 : 1, α : β). Hydrogenolysis of the benzyl ether groups resulted in tutin double-bond migration. Epoxide opening and rearrangement were observed upon acetylation of the tutin glucoside.

Gadolinium complexes are widely applied as magnetic resonance imaging contrast agents. However, they have some undesirable properties, e.g. low relaxivity and target non-specificity. A new biocompatible macromolecular gadolinium compound has been synthesised as a liver-specific contrast agent. The ability to improve the imaging signal and the T₁-relaxivity is satisfactory, and it has a long window imaging time with a low acute toxicity.

Two novel zinc coordination polymers have been synthesised and characterised. Their topological structures show 4-connected 8- and 3-fold interpenetrating 3D frameworks. Furthermore, they exhibit good photodegradation capability and photoluminescence properties.

Cedar powder was treated with ionic liquids and onium hydroxide aqueous solution under very mild condition such as at 60°C. Addition of hydrogen peroxide accelerated the dissolution of lignin fragments with larger molecular weights owing to scission of the lignin network structure.

Intramolecular H···H as well as C···H non-covalent interactions have been retrieved and characterized using quantum theory of atoms-in-molecules and the computed chemical reactivity index using HOMO–LUMO gap and molecular electrostatic potential surface have been compared with experimentally observed bioactivity parameter.

Although PhI(OAc)₂ is known as an oxidizing agent, it can also serve as a reagent or a catalyst in different types of chemical reactions in organic synthesis. PhI(OAc)₂ is used in radical reactions, oxidation reactions, and in heterocycle synthesis. This paper reports some relevant and recent new uses of PhI(OAc)₂.
