Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 484-47-9, is researched, Molecular C21H16N2, about Sulfonated-polyvinyl amine coated on Fe3O4 nanoparticles: a high-loaded and magnetically separable acid catalyst for multicomponent reactions, the main research direction is sulfonated polyvinyl amine coated iron oxide nanoparticle catalyst property; multicomponent reaction imidazole synthesis.Product Details of 484-47-9.

In this study, a PVAm-bearing SO3H groups/Fe3O4 nanocomposite was prepared via a simple and in situ polymerization of acrylamide onto the surface of magnetic nanoparticles without using organosilane precursors. In order to obtain amine-functionalized magnetic, Hofmann degradation was carried out. In the following, sulfonated-polyvinyl amine coated on Fe3O4 nanoparticles was prepared by covalent grafting of chlorosulfonic acid on amine groups. The introduction of polymer to the surface of magnetic nanoparticles increases the loading content with functional groups extremely. The resulting hybrid material was effectively employed as an unprecedented acid magnetic catalyst for the one-pot synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles under solvent-free conditions. High yields, mild reaction conditions, short reaction times, operational simplicity with reusability are the notable features of the catalyst. The structure of the newly developed catalyst was characterized using TGA, FT-IR, SEM, TEM, VSM, EDX, CHNS, and XRD anal. Magnetic separation and recycling of the catalyst for at least 8 runs is possible without any significant deterioration in catalytic activity. This work is the first report of employing PVAm as a linker for immobilizing liquid acid on a support.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Nature Communications called Thermochemiluminescent peroxide crystals, Author is Schramm, Stefan; Karothu, Durga Prasad; Lui, Nathan M.; Commins, Patrick; Ahmed, Ejaz; Catalano, Luca; Li, Liang; Weston, James; Moriwaki, Taro; Solntsev, Kyril M.; Naumov, Pance, which mentions a compound: 484-47-9, SMILESS is C1(C2=CC=CC=C2)=NC(C3=CC=CC=C3)=C(C4=CC=CC=C4)N1, Molecular C21H16N2, Related Products of 484-47-9.

Chemiluminescence, a process of transduction of energy stored within chem. bonds of ground-state reactants into light via high-energy excited intermediates, is known in solution, but has remained undetected in macroscopic crystalline solids. By detecting thermally induced chemiluminescence from centimeter-size crystals of an organic peroxide here we demonstrate direct transduction of heat into light by thermochemiluminescence of bulk crystals. Heating of crystals of lophine hydroperoxide to ~115 ° results in detectable emission of blue-green light with maximum at 530 nm with low chemiluminescent quantum yield [(2.1 ± 0.1) x 10-7 E mol-1]. Spectral comparison of the thermochemiluminescence in the solid state and in solution revealed that the solid-state thermochemiluminescence of lophine peroxide is due to emission from deprotonated lophine. With selected 1,2-dioxetane, endoperoxide and aroyl peroxide we also establish that the thermochemiluminescence is common for crystalline peroxides, with the color of the emitted light varying from blue to green to red.
