Synthesis and spectral properties of novel fluorescent diethoxycarbonyl glycoluril derivatives
A novel class of fluorescent diethoxycarbonyl glycoluril derivatives with aryl alkyne side chains was synthesized via alkylation and subsequent Sonogashira cross-coupling reactions. The fluorescence spectra showed that these compounds exhibited good blue fluorescence with the maximum wavelengths ranging from 368 nm to 403 nm. Georg Thieme Verlag Stuttgart.

Synthesis and binding properties of two new fluorescent molecular clips based on diethoxycarbonyl glycoluril
Two new fluorescent molecular clips based on diethoxycarbonylglycoluril have been synthesised and their binding properties investigated by fluorescence spectroscopy to show that they can selectively bind Fe3+ with fluorescence quenching.

Synthesis of self-folded molecular rotors controlled by edge-to-face CH/π aromatic interactions
A series of novel self-folded molecular rotors were synthesized and characterized by 1H NMR, 13C NMR, HRMS, and IR data. All but two compounds were also studied by X-ray crystallography. Georg Thieme Verlag Stuttgart.

Sensor for nitrophenol based on a fluorescent molecular clip
We report the synthesis, X-ray crystal structure, and photophysics of a fluorescent molecular clip (1). Binding studies of 1 toward phenols 2a-j were carried out using fluorescence, 1H NMR, and IR spectroscopy, which revealed a high affinity and selectivity for 4-nitrophenol (2a) due to formation of the 1-2a complex driven by H-bonding and π-π stacking interactions.

A novel method of synthesis of 1,2-diketones from 1,2-diols using N-bromosuccinimide
A simple and convenient procedure is reported for the synthesis of benzils and aliphatic 1,2-diketones of cyclic and open chain compounds from corresponding hydrobenzoins and 1,2-diols by refluxing with N-bromosuccinimide in carbon tetrachloride in presence or absence of pyridine.

Oxidation of cobalt (III) bound and unbound oxalacetic acid by potassium bromate
The title reaction exhibits total second order kinetics.To explain the formation of products, diketosuccinic acid/CoIII-diketosuccinic acid and stoichiometric results, a suitable mechanism has been proposed.

Kinetics of the Reaction of Iodine with Dihydroxyfumaric Acid
The kinetics of the reaction of dihydroxyfumaric acid (DFH4) with I2 and I3- have been investigated and it has been shown that the reaction between DFH4 and I2 is very rapid (k > 2 x 107 litre mol-1 s-1), but subsequently the rate is limited by the conversion of the keto-form of the acid into the enediol form.With increase of the concentration of iodide ions, the rate of oxidation of DFH4 falls (k = 6.9 litre mol-1 s-1).The optimum conditions for the application of the reaction of I2 with DFH4 to the determination of the content of the enediol form of the acid in the dihydroxyfumaric acid-oxaloglycolic acid tautomeric mixture have been found.

Catalysis of the Oxidation of Dihydroxyfumaric Acid. Kinetics and Mechanism of the Oxidation of Dihydroxyfumaric Acid by Hydrogen Peroxide in the Presence of Iron(II) Ions
The Fe2+-dihydroxyfumaric acid (DFH4)-H2O2 system has been investigated by the kinetic grid method.The reaction is of first order with respect to Fe2+, DFH4, and H2O2, and its rate depends only slightly on the pH.The effective rate constants for reactions involving complexes with the mono- and di-anions have been estimated.It is shown that the oxidation of DFH4 by hydrogen peroxide proceeds in the same way as the oxidation by oxygen-via a cyclic mechanism.

The Kinetics and Mechanism of the Oxidation of Dihydroxyfumaric Acid by Oxygen in the Presence of Iron(II) Ions
The kinetics and mechanism of the oxidation of dihydroxyfumaric acid by oxygen, catalysed by Fe2+ ions, have been investigated by spectrophotometric and gas-volumetric methods.An expression has been obtained for the rate of oxidation and for the estimation of the effective rate constants.A cyclic mechanism is proposed.

Catalysis of the Oxidation of Dihydroxyfumaric Acid. V. The Machanism of the Oxidation of Dihydroxyfumaric Acid by Oxygen in the Presence of Copper Ions
Using acetonitrile and allyl alcohol as additives, it has been established that the oxidation of dihydroxyfumaric acid by oxygen in the presence of copper ions proceeds via a chain mechanism.It is shown that the rate of the catalytic reaction is related to the rate of generation of Cu+ by the expression characteristic of chain processes with quadratic chain termination in which the reaction of Cu+ with O2 is the chain propagation reaction.
