Dicumyl Peroxide used as curing Agent for different Types of Rubber Matrices Part I: Effect of Temperature

Several elastomers were cured with dicumyl peroxide at different vulcanization temperatures. The focus of the work was the investigation of the influence of curing temperature on curing characteristics of rubber compounds. Subsequently, crosslink density and physical mechanical properties of vulcanizates were evaluated. The results demonstrated that higher curing temperatures lead to a total acceleration of cross-linking process. The effect of temperature on the crosslink density was low and was dependent on the structure of tested rubbers. Physicalmechanical properties of vulcanizates were almost not influenced by curing temperature.

An electrochemical alternative approach to the cyclization of alkynes bearing proximate malonyl moieties

A versatile alternative approach to the synthesis of butenolides, quinolones and 3-pyrrolin-2-ones has been achieved by galvanostatic electrolysis of MeCN/TEATFB solutions and subsequent addition of the cathodic solution to alkynes bearing proximate malonyl moieties. The electrogenerated cyanomethyl anion permits the formation of the reactive anionic intermediates under mild conditions, avoiding the need to use classical bases. ((C) Wiley-VCH Verlag GmbH & Co.

Studies on the in vivo biotransformation of the tobacco alkaloid beta-nicotyrine

This paper reports the results of studies on the in vivo metabolic fate of the tobacco alkaloid 1-methyl-2-(3-pyridinyl)pyrrole (beta-nicotyrine) in New Zealand white rabbits. Two previously characterized metabolites, 5-hydroxy-1-methyl-5-(3-pyridinyl)-2-pyrrolidinone (5-hydroxycotinine) and 2-hydroxy-1-methyl-5-(3-pyridinyl)-3-pyrrolin-2-one, were present in low concentrations in the urine of the treated animals. The major urinary metabolite of beta-nicotyrine was identified as cis-3′-hydroxy-1-methyl-5-(3-pyridinyl)-2-pyrrolidinone (cis-3′-hydroxycotinine), the diastereoisomer of the major urinary metabolite of (S)-nicotine. The pathway leading to cis-3′-hydroxycotinine is proposed to proceed via autoxidation of 2-hydroxy-1-methyl-5-(3-pyridinyl)pyrrole, a postulated cytochrome P450-generated metabolite of beta-nicotyrine, followed by reduction of the carbon-carbon double bond present in the resulting 3-hydroxy-3-pyrrolin-2-one species. This proposal is supported by the in vivo biotransformation of 2-acetoxy-1-methyl-5-(3-pyridinyl)pyrrole, a latent form of the putative hydroxypyrrole intermediate, to cis-3′-hydroxycotinine. The in vivo conversion of 5-hydroxy-1-methyl-5-(3-pyridinyl)-3-pyrrolin-2-one to 5-hydroxycotinine is offered as evidence that supports the proposed reduction step.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. In my other articles, you can also check out more blogs about 256-96-2. Recommanded Product: 5H-Dibenzo[b,f]azepine.

Acid promoted dimerization of beta-amino-alpha,beta-unsaturated amides affording bis(functionalized) pyrrolinones

Polysubstituted pyrrolinones were synthesized by the dimerization of 3-amino-2-butenamides via treatment with 0.5 equiv p-TsOH under mild reaction conditions, including oxidation and 1,2-migration of the methyl group. This method is practically advantageous compared to the conventional methods for the preparation of pyrrolinones, because it does not require difficult experimental manipulations and special reagents such as metal catalysts and oxidants. Because the structures of beta-amino-alpha,beta-unsaturated amides can be easily modified by changing the precursors, beta-keto amide and amine, synthesis of diverse pyrrolinones is possible.

Catalyst-Free [4+2] Cycloaddition of Ynamides with 2-Halomethyl Phenols To Construct 2-Amino-4H-Chromenes and alpha-Halo Enamides Simultaneously

We report the development of a facile protocol for the [4+2] cycloaddition of ynamides and 2-halomethyl phenols to afford the corresponding 2-amino-4H-chromenes and alpha-halo enamides under catalyst-free conditions. The reaction proceeds under mild conditions and exhibits good tolerance toward various functional groups and generates high yields. The plausible mechanism involves the formation of an active intermediate keteniminium as well as o-methylene quinone.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 293298-33-6.

Two new coordination compounds viz. [Ni(2,6-PDC)(Hdmpz)(H2O)(2)]center dot H2O (1) and [Zn(3-CNpy)(2)Cl-2] (2) (2,6-PDC = 2,6-pyridinedicarboxylate, Hdmpz = 3,5-dimethylpyrazole, 3-CNpy = 3-cyanopyridine) have been synthesized and characterized using elemental analysis, thermogravimetric analysis, electronic, infrared spectroscopy and single crystal X-ray diffraction techniques. Crystal structure analyses reveal the presence of supramolecular assemblies involving interesting dimers with unconventional contacts in the compounds. DFT (Density Functional Theory) calculations on the supramolecular dimers in the crystal structure of 1 reveal that the sum of contributions of anion-pi, pi-pi and other long range interactions due to the approximation of the bulk monomers is energetically significant. Molecular Electrostatic Potential (MEP) surface and Quantum Theory of Atoms in Molecules (QTAIM) analyses on the interesting supramolecular dimers of the crystal structures of 2 reveal the presence of unconventional anion center dot center dot center dot pi contacts involving coordinated chlorido ligands and C-H center dot center dot center dot pi(nitrile) interactions involving the pi-system of the nitrile moiety of 3-cyanopyridine. Remarkably, Atoms in Molecules analysis also confirms the existence of energetically significant unconventional anti-parallel nitrile center dot center dot center dot nitrile interaction in the crystal structure of 2. Cell cytotoxicity of the compounds performed in Dalton’s lymphoma (DL) malignant cancer cell line showed effective potency with negligible cytotoxicity in normal cells (similar to 12%). It is interesting that compound 1has excellent cytotoxic potency with IC50 closer to cisplatin and can bind different biological targets with similar signalling pathways.

Involvement of esterase in phytotoxicity of a new pyrrolinone compound, methyl 1-[1-(3,5-dichlorophenyl)-1-methylethyl]-2,3-dihydro-4-methyl-2-oxo-3-phenyl-1H-pyrrole-3-carboxylate, to early watergrass (Echinochloa oryzicola) and rice (Oryza sativa)

A new pyrrolinone compound, methyl 1-[1-(3,5-dichlorophenyl)-1-methyl ethyl] -2,3-dihydro-4-methyl-2-oxo-3 phenyl-1H-pyrrole-3-carboxylate (PC-1), has herbicidal activity against early watergrass (Echinochloa oryzicola). This compound showed good selectivity between rice (Oryza sativa) and early watergrass due to the introduction of a methoxycarbonyl group into the Pyrrolinone structure. To elucidate the mechanism of PC-Is phytotoxicity, the effects of esterase inhibitors (triphenyl phosphate, tributyl phosphate and fenitrothion) and a cytochrome P450 monooxygenase inhibitor (1-aminobenzotriazole) on the actions of PC-I were examined. Triphenyl phosphate and fenitrothion reduced the phytotoxicity of PC-1 in hydroponics and greenhouse tests. Porcine liver esterase converted PC-1 to 1-[1-(3,5-dichiorophenyl)-1-methylethyl]-4-methyl-3-phenyl-3-pyrrolin-2-one (PC-2) and this reaction was inhibited by triphenyl phosphate. The PC-2 content of early watergrass treated with PG I was 4 times that of rice. These results suggest that PG I is a prodrug and is converted to PC-2 by esterase, and that the amount of PC-2 produced in PC-1-treated plants is related to the sensitivity of early watergrass and rice to PC-1.
