Sulfonic Acid-Functionalized Silica-Coated Magnetic Nanoparticles as a Reusable Catalyst for the Preparation of Pyrrolidinone Derivatives Under Eco-Friendly Conditions

The surface of silica-coated CoFe2O4 magnetic nanoparticles (CoFe2O4@SiO2), which is resistant to the oxidation due to silicone coating, was functionalized using chlorosulfonic acid and used as an efficient and recyclable catalyst for the preparation of 3-pyrrolin-2-ones from diethyl acetylenedicarboxylate, an aldehyde and aniline in ethanol solvent at 60 degrees C. In the presented study, some fascinating chracteritics of such catalyst, such as magnetically separable, simple workup and obtaining a high purity of products by simple recrystallization, have been successfully obtained. The structural features of CoFe2O4@SiO2-SO3H catalyst were elucidated by X-ray powder diffraction (XRPD), thermo-gravimetric studying (TGA), scanning electron microscopy (SEM) and FT-IR spectra.

An EPR study of wheat seeds by the use of nitroxide spin probes

The viability of a variety of wheat seeds Mas investigated by use of the EPR technique, Three different types of spin probes (4-Hydroxy-TEMPO (TANOL), 3-Carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy, 3-Carbamoyl-PROXYL) were utilized in examining the viability of embryo cells. The penetration of the spin probe across the membrane was observed via the change in signal intensity against time for dry embryos of the variety of wheat seeds soaked in aqueous solutions of spin probe and line broadening agent. From the analysis of the signal intensity-time curves (i.e. rehydration curves) it was observed that the two kinds having different genetic roots (Bezostaya, Kunduru) exhibit similar saturation behaviour whereas Gerek saturates much more easily. The rehydration curves for naturally aged seeds indicates that aging causes rapid saturation and an important decrease in the signal intensity. In order to get better insight on the effect of the signals from polar and nonpolar regions on the experimental spectra, these spectra were simulated by the use of the theoretical models developed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 578-95-0. COA of Formula: https://www.ambeed.com/products/578-95-0.html.

Synthesis of Highly Substituted 3-Pyrrolin-2-ones from N,N-Disubstituted alpha-Amino Acids

Highly functionalized 5-membered N-heterocyclic compounds, 4-aryl-3-chloro-5-methoxy-1-methyl-3-pyrrolin-2-ones, have been synthesized in moderate to high yields by the reaction of N,N-dimethylated aromatic alpha-amino acids with oxalyl chloride, followed by solvolysis with MeOH. The products possess a number of functional groups such as an amide, a mixed amido/alkoxy acetal, a vinyl halide, and an alkene and thus are promising candidates to be used as starting materials for the synthesis of diverse five-membered N-heterocyclic compounds.

The vibrational group frequency of the N-O-center dot stretching band of nitroxide stable free radicals

The group frequency of the N-O radical stretching vibration has received scant attention in the literature. The few existing treatments of the vibrational spectroscopy of nitroxides are incomplete at best and potentially misleading to workers in the field. To close this gap in the available knowledge, the existing literature on the vibrational spectra of nitroxide stable free radicals is critically reviewed with particular reference to the wavenumber position of the N-O-center dot stretching vibration, nu(N-O-center dot). Poor evidentiary bases for the assignment nu(N-O-center dot) were found in many instances. Ab initio Density Field Theory calculations using a model chemistry of UB3LYP at the 6-311 ++G(d,p) level were performed to obtain a theoretical band position of nu(N-O-center dot) for comparison with the published data. Large discrepancies between the theoretical and experimental values were found for the radical 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxyl, which currently sets the lower limit of the accepted wavenumber range of nu(N-O-center dot), as well as for the nitronyl and iminyl nitroxides. The wavenumber position of nu(N-O-center dot) was found to occur in the range 1450-1420cm(-1) for 5-membered cyclic nitroxides and 1395-1340 cm(-1) for 6-membered cyclic and acyclic nitroxides. In nitronyl nitroxides, the symmetric stretching vibration occurs in the region 1470cm(-1), but coupling to other modes makes specific band assignments problematic for the nitronyl nitroxide group.

Cross-Linking of Rubber Matrices with Dicumyl Peroxide and Zinc Dimethacrylate. Part I: Effect of Co-Agent Content

The work is focused on the investigation of the influence of the amount of co-agent on cross-linking and properties of rubber compounds. The in-situ radical polymerization of zinc dimethacrylate occurs during the curing process of rubber compounds with organic peroxide. Polymerized zinc dimethacrylate tends to form different types of chemical and physical linkages within the rubber matrices. As the amount of dimethacrylate ranged from 10 to 50 phr, the conversion of zinc dimethacrylate remained low. Residual zinc dimethacrylate formed micro-dispersion in the rubber matrix. The dispersion and distribution of zinc dimethacrylate in the rubber depends on the viscosity of matrix, shear stress and polarity of the matrix. Despite low conversion of zinc dimethacrylate, the application of co-agent resulted in the increase of cross-link density and improvement of physical-mechanical properties of vulcanizates.

Insecticidal, anti-juvenile hormone, and fungicidal activities of organic extracts from different Penicillium species and their isolated active components

Organic extracts from mycelium and culture broth of 21 Penicillium isolates have been tested for insecticidal, insect anti-juvenile hormone (anti-JH), and antifungal activities. Culture broth extracts were the most active, mainly against insects; nearly 25% of them have shown high entomotoxicity (100% mortality at 100 mu g/cm(2)). A strong in vivo anti-JH activity against Oncopeltus fasciatus Dallas was detected in the culture broth extracts from P. brevicompactum P79 and P88 isolates. The two new natural products isolated from P79, N-(2-methyl-3-oxodec-8-enoyl)-2-pyrrolin (1) and 2-hept-5-enyl-3-methyl-4-oxo-6,7,8, 8a-tetrahydro-4H-pyrrolo[2,1-b]-1,3-oxazine (2), possessed anti-SN and insecticidal activity, respectively, against O. fasciatus. Synthesized natural compound 1 has-shown an ED50 of 0.7 mu g/nymph when assayed on newly molted fourth-instar nymphs of O. fasciatus. Promising biological activities have also been detected in the synthetic precursors.
