Synthesis of some isoxazoline, isoxazole and pyrazole carboxylic acids as the precursors of new 1,2-diacyl-1-alkylhydrazines [PDF]
A number of isoxazoline, isoxazole and pyrazole carboxylic acids or their esters has been synthesized via the 1,3-dipolar cycloaddition of corresponding nitrile oxides or diazomethane to unsaturated dipolarophiles.

Palladium(II) complexes with a phosphino-oxime ligand: synthesis, structure and applications to the catalytic rearrangement and dehydration of aldoximes [PDF]
The treatment of [PdCl2(COD)] (COD = 1,5-cyclooctadiene) with 1 and 2 equivalents of 2-(diphenylphosphino)benzaldehyde oxime in dichloromethane at room temperature led to the selective formation of [PdCl2{κ2-(P,N)-2-Ph2PC6H4CH[double bond, length as m ...

Anisometric carbon nanodots are synthesized directly from a liquid crystal precursor and embedded into polymer network liquid crystals to create soft, multifunctional photonic films. These hybrid devices exhibit polarized photoluminescence, broad UV absorption, and fast, electrically tunable light modulation.

Bipolar Hydrogen Production by Hybrid Water Electrolysis
This review focuses on the recent advances in uniqueness bipolar H2 production from the oxidation of representative small molecules, including 5‐hydroxymethylfurfural, formaldehyde, alcohols, and N‐heterocycle amides. The target electrocatalysts and the underlying mechanisms are discussed in respect to specific substrate oxidation.

Tailoring the Properties of Functional Materials With N‐Oxides
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Reaction of pyrroles with ethyl 2-nitroso- and 2-azo-propenoates, and with ethyl cyanoformate N-oxide: a comparison of the reaction pathways [PDF]
The reaction of ethyl 2-nitrosopropenoate 2a with 1 -methylpyrrole, 2.5-dimethylpyrrole and 2.5- diphenylpyrrole has been investigated. In every case the products result from highly regioselective attack at C-2 of the pyrrole by the electrophile.
