Vacuum-Ultraviolet Absorption Spectrum of 3-Methoxyacrylonitrile

The high-resolution absorption spectrum of 3-methoxyacrylonitrile (3MAN) was measured between 5.27 and 12.59 eV using a synchrotron-based Fourier-transform spectrometer. It was related to an absolute absorption cross-section scale. Complementary calculations at the DFT-MRCl/aug-cc-pVTZ level of theory document the vertical transition energies and oscillator strengths toward the first 19 states of both the E and Z geometrical isomers of 3MAN. Comparisons with the experimental absorption spectrum reveal the similarities and differences between 3MAN, a bifunctional molecule, with acrylonitrile and methyl-vinylether, where only one functional group is present. As in acrylonitrile, several broad valence transitions were observed up to the ionization limit. They are likely associated with the extended pi-system induced by the nitrile group but might also involve sigma sigma* transitions close to the ionization limit. As in methylvinylether, Rydberg series converging to the ionization limit are absent. This is attributed to a difference in neutral and cationic geometry due to a 60 degrees rotation of the methyl group.

Cu(II)-catalyzed cyclization of alpha-diazo-beta-oxoamides with amines leading to pyrrol-3(2H)-ones

A novel Cu(II)-catalyzed cyclization of alpha-diazo-beta-oxoamides with amines has been developed, constituting a straightforward method to construct pyrrol-3(2H)-one rings. The intramolecular hydrogen bonding effect in alpha-diazo-beta-oxoamides plays an essential role in this reaction. A plausible reaction mechanism involving divergent generation and subsequent [2 + 3] cyclization of ketene and alpha-diazoimine intermediates was proposed.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.

Preparation of pyrrolin-2-ones and 4,5-dihydrodipyrrin-1-ones by oxidation of alpha-formylpyrroles and alpha-formyldipyrromethanes with hydrogen peroxide

Various substituted alpha-formylpyrroles and -dipyrromethanes have been oxidized by hydrogen peroxide under mild conditions to give pyrrolin-2-ones (2) and 4,5-dihydrodipyrrin-1-ones (4) with concomitant loss of the formyl substituent, thus extending the scope of this oxidation to dipyrromethanes. This makes the reaction especially useful for the preparation of bile pigments, for which the pyrrolinones and 4,5-dihydrodipyrrinones constitute important synthons. (C) 2000 Elsevier Science Ltd.

Piperonylonitrile solubility in thirteen pure solvents: Determination, Correlation, Hansen solubility parameter, solvent effect and thermodynamic analysis

This work was to investigate piperonylonitrile in terms of its solid-liquid equilibrium solubility in thirteen pure solvents by employing laser monitoring technique. Solubility measurements were completed in range of temperature at (288.15-323.15) K in 1,4-dioxane and at (278.15-323.15) K in isopropanol, 2-methoxyethanol, ethanol, ethyl acetate, methanol, n-propanol, n-propyl acetate, N,Ndimethylformamide (DMF), isopropyl acetate, methyl acetate, acetone as well as acetonitrile under 0.1 MPa. The holistic solubility profile showed that piperonylonitrile solubility in all measured solvents was proportional to the increasing of test temperature. It was also found that the mole-fraction solubility values of piperonylonitrile in measured solvents at 298.15 K exhibited a sequence of: DMF (0.2636) > 1,4dioxane (0.2212) > methyl acetate (0.1838) > acetone (0.1813) > ethyl acetate (0.1657) > n-propyl acetate (0.1486) > acetonitrile (0.1435) > isopropyl acetate (0.1295) > 2-methoxyethanol (0.1010) > methanol (0.01915) > ethanol (0.01664) > n-propanol (0.01594) > isopropanol (0.01268). The miscibility and solubility order of piperonylonitrile were further revealed by the means of Hansen solubility parameter, demonstrating that solubility behaviors could be well explained by the comprehensive action of various solubility parameters. Besides, the influence on the piperonylonitrile solubility of solute-solvent interaction and solvent-solvent interaction was illustrated via the KAT-LSER model. It was figured out that hydrogen bonding acidity and hydrogen bonding basicity exerted unfavorable influence on piperonylonitrile solubility. Moreover, the measured piperonylonitrile solubility was fitted with Wilson, NRTL, UNIQUAC, Two-Suffix Margules and NRTL-SAC model, and correlation of experimental results with the use of five activity coefficient models showed that sufficient agreement with the calculated data. Finally, the thermodynamic quantities (Delta H-mix, Delta(mix)G and Delta S-mix) of the mixing process in different solvents were computed based on measured solubility values and UNIQUAC model. The results demonstrated that the mixing process was entropy-driven and spontaneous. (c) 2020 Elsevier Ltd.

Synthesis of 3-Alkoxy-4-Pyrrolin-2-ones via Rhodium(II)-Catalyzed Denitrogenative Transannulation of 1H-1,2,3-Triazoles with Diazo Esters

A method for the synthesis of densely substituted 4-pyrrolin-2-ones by Rh(II)-catalyzed denitrogenative transannulation of 1-alkyl-4-aryl-1H-1,2,3-triazoles with diazo esters has been developed. The reaction proceeds via an attack of the rhodium-bound carbene at the N2 atom of the triazole and the formation of unstable 3,4-dihydro-1,2,4-triazine, which further undergoes ring contraction to a 4-pyrrolin-2-one under rhodium catalysis. The method is inapplicable to 1,2,3-triazoles with primary alkyl substituent at C4, which afford stable 1,2,3-triazol-3-ium ylides as the main products.

Targeted development of hydrophilic porous polysulfonamide gels with catalytic activity

We report the use of a template and functional monomers in the synthesis of three novel polysulfonamide gels with new architectures and functional groups. These mesoporous polysulfonamide gels were prepared by the condensation polymerization of benzene-1,3-disulfonyl chloride (as the main precursor), linear monomers, and cross-linkers (as variable precursors) in the presence of a silica template by a combination of sol-gel chemistry and the nanocasting technique. In this synthesis pathway, in situ polymerization onto the template surface led to the construction of a silica/polymer nanocomposite. Next, after removal of the template, the nanocomposite gels were transformed into mesoporous polysulfonamide nanospheres. After the physicochemical identification of the synthesized materials, functionalized polysulfonamides were used as reusable novel catalysts with high efficiency for the Strecker reaction under mild conditions. These polymers have Brunsted/Lewis acid active sites, a mesoporous structure, and hydrogen bonding. Moreover, since these polymers are hydmgels that can absorb water, they can promote the Strecker reaction through chemical absorption of the generated water as a driving force. Overall, this article describes a novel synthesis procedure and application of porous polysulfonamide gels.

Acid-catalyzed rearrangement of 1-acyl-2-azabuta-1,3-dienes to 4-pyrrolin-2-ones

1-Acyl-2-azabuta-1,3-dienes underwent rearrangement to 4-pyrrolin-2-ones in the presence of acidic catalysts (silica gel or ZnCl2) and water. The reaction proceededviathe formation of 2,3-dihydroxy-3,4-dihydropyrrole and 2-hydroxy-2H-pyrrole intermediates, the latter of which was transformed by [1,5]-sigmatropic shift of carbonyl substituent and prototropic isomerization. 4-Chloro-substituted 1-acetyl-2-azabuta-1,3-dienes were stable toward rearrangement, while brominated analogs rearranged into 4-pyrrolin-2-ones, probably as a result of the initial radical hydrodebromination. According to calculations performed at the DFT level, two steps of the reaction were catalyzed by acid: the cyclization of 2-azabutadiene and the sigmatropic shift in the 2-hydroxy-2H-pyrrole intermediate.
