A catalyst-free and recycle-reinforcing elastomer vitrimer with exchangeable links

Vitrimers, as intriguing polymers, possess exchangeable links in the crosslinking networks, endowing them with the abilities of recycling and reprocessing. However, most of vitrimers are generally fabricated via complex synthesis and polymerization processes. Toxic and unstable exogenous catalysts are inevitably applied to activate the exchange reaction to rearrange the crosslinking networks. These drawbacks limit the widespread applications of vitrimers. Moreover, most reported vitrimers could only partially maintain or severely deteriorate their mechanical properties after recycling. Herein, to solve the above-mentioned problems, for the first time, a catalyst-free and recycle-reinforcing elastomer vitrimer is revealed. By the reactive blending of commercially available epoxidized natural rubber and carboxylated nitrile rubber, the elastomer vitrimer associated with exchangeable beta-hydroxyl ester bonds was obtained. Strikingly, the vitrimer exhibits an exceptional recycle-reinforcing property. This work provides a feasible method to fabricate elastomer vitrimers, which promotes the recycling of crosslinking commercial available elastomers.

Studies on the oxidation of 2,2,4-trisubstituted 3-pyrrolines

As part of our studies directed towards a total synthesis of lactacystin, we have developed a reliable and environmentally acceptable method to oxidise 2,2,4-trisubstituted 3-pyrrolines to the corresponding 3-pyrrolin-2-ones. Several protocols were examined and the two-step (i) TPAP/NMO; (ii) sodium hypochlorite allylic oxidation was found to be the most satisfactory. Catalytic oxidation of the 3-pyrroline afforded the corresponding cyclic imine in high yield, and subsequent oxidation with NaOCl afforded the N-chloro-3-pyrrolin-2-one. The N-chloro-substituent was removed by a simple acid treatment. (C) 2002 Published by Elsevier Science Ltd.

Solubility measurement, model evaluation and Hansen solubility parameter of piperonylonitrile in four binary solvents

The present research work proposed the mole fraction solubility and mixing thermodynamic properties of piperonylonitrile in different binary solvent mixtures such as ethanol + (acetone, 1,4-dioxane, DMF and methyl acetate) at T = 278.15 K to 323.15 K and p = 0.1 MPa. The results indicated that as the temperature and mass fraction of positive solvents increased, the measured solubility of piperonylonitrile increased in all mixtures considered. Analysis using Hansen solubility parameter revealed that the affinity between piperonylonitrile and all mixed solvents was related to multiple factors. The experimental solubility of piperonylonitrile in four binary solvent mixtures was regressed by employing four thermodynamic models such as UNIQUAC, Margules, Wilson and NRTL model. It was found that the Wilson model was accurate enough to correlate the experimental solubility. Moreover, the mixing thermodynamic properties of piperonylonitrile in different mixed solvents were also estimated and discussed according to the Wilson model and experimental data. The results of the negative Delta(mix)G values and positive Delta S-mix values demonstrated the entropy-driven and spontaneous mixing process of piperonylonitrile in all binary solvent mixtures.

Synthesis of Benzo[a]carbazoles and an Indolo[2,3-a]carbazole from 3-Aryltetramic Acids

A simple and flexible approach to 3-pyrrolin-2-one fused carbazoles is disclosed. The key step involves the BF3-mediated electrophilic substitution of indoles with N-alkyl-substituted 3-aryltetramic acids, which provides access to indole-substituted 3-pyrrolin-2-ones. Scholl-type oxidative cyclizations of these materials led to the formation of the corresponding 3-pyrrolin-2-one-fused benzo [a]carbazoles and indolo[2,3-a]carbazoles. This work represents the first synthesis of the benzo [a]pyrrolo[3,4-c]carbazol-3(8H)-one ring system, while the indolo[2,3-a]pyrrolo[3,4-c]carbazol-5-one ring system is found in a number of biologically active compounds including the protein kinase C (PKC) inhibitor, staurosporine.

Microwave-induced free radicals production in red wine and model wine by electron paramagnetic resonance spin trapping

Microwave can directly induce the production of 1-hydroxyethyl free radical in red wine and model wine. Free radicals are considered as key intermediates in the wine aging processing by microwave, but their properties have not been determined. Electron paramagnetic resonance (EPR) spin trapping with 5,5-dimethyl-1-pyrrolin N-oxide (DMPO) was used to detect the type of free radicals. After microwave irradiation, spin adducts of hydroxyl free radical were detected in DMPO solution, whereas 1-hydroxyethyl free radical spin adducts were captured in red wine and model wine, because 1-hydroxyethyl free radicals arose from the oxidation of ethanol by hydroxyl free radical in red wine induced by microwave irradiation. Compared with the processing of natural oxidation, the intensity of free radicals induced by microwave in red wine became more strong, and the effects of microwave temperature, time, and power on the intensity of 1-hydroxyethyl free radical spin adducts in model wines were also studied. The intensity of free radical spin adducts increased with the increasing of microwave power and time. The intensity of DMPO/1-hydroxyethyl free radical spin adducts increases at low temperature, but decreased at higher temperatures. Practical applications This study investigated the existence of free radical in the processing of wine aging, and the possible mechanism of microwave irradiation accelerated aging of red wine was studied with model wine. Results revealed that the intensity of 1-hydroxyethyl free radical induced by microwave in red wine and model wine. Therefore, microwave irradiation was considered to be a promising aging technology, so microwave radiation technology can be used in many aging products that sped up the aging processing.

Water-soluble xanthobilirubinic acids?

Xanthobilirubinic acid, a model dipyrrinone for one-half of the bilirubin molecule in photochemical and metabolism studies, is more polar than bilirubin and insoluble in water and in chloroform. Replacing the b- alkyl substituents on the lactam ring of xanthobilirubinic acid with methyl-capped ethylene glycol, diethylene glycol, and triethylene glycol (PEG) groups steadily increased the water solubility of the pigment so that the last is completely soluble in both water and chloroform. Synthesized by base-catalyzed condensation of the corresponding methyl-capped 3,4-diPEG-pyrrolin-2-one with 3,5-dimethyl-4(2-ethoxycarbonylethyl)-2-formyl-1H-pyrrole, these new PEGylated analogs of xanthobilirubinic acid are yellow-colored dipyrrinones that form intermolecular hydrogen-bonded dimers in chloroform solution but are monomeric in methanol and water, as revealed by H-1 NMR spectroscopy and vapor pressure osmometry. Methyl xanthobilirubinate has served as a synthetic precursor to bilirubinoids; its amphiphilic PEGylated analogs suggest a route to water-soluble bilirubinoids and biliverdinoids.
