The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1-(Furan-2-yl)propan-1-one(SMILESS: O=C(C1=CC=CO1)CC,cas:3194-15-8) is researched.Reference of (R)-Piperidin-3-ol hydrochloride. The article 《Hydrothermal formation of hydroxylated benzenes from furan derivatives》 in relation to this compound, is published in Journal of Analytical and Applied Pyrolysis. Let’s take a look at the latest research on this compound (cas:3194-15-8).

Several furan derivatives were subjected to hydrothermolysis at 340° and 27.5 MPa for 1-33 min in a flow system to study their conversion to hydroxylated benzenes. Hydrothermolysis of 0.05M aqueous 5-methyl-2-furaldehyde, 2-acetylfuran and 2-propionylfuran gave 1,4-benzenediol, 1,2-benzenediol and 3-methyl-1,2-benzenediol, resp., with selectivities ranging from 10-65%. Hydrothermolysis of 0.01M aqueous 2-acetyl-5-(hydroxymethyl)furan and 5-(1-hydroxyethyl)-2-furaldehyde did not produce the expected benzenetriols; instead, 2-methyl-1,4-benzenediol could be identified as a product. Hydrothermolysis of 2-vinylfuran did not produce any phenol, an indication that the formation of benzene rings from furans is not accomplished by electrocyclic ring closure. 2,6-Dimethyl-γ-pyrone, a compound that is known to produce 5-methyl-1,3-benzenediol via an aldol condensation under alk. conditions, also gave this product under hydrothermal conditions. A reaction pathway for the hydrothermal formation of hydroxylated benzenes from furan derivatives is presented which is based on C ring formation via an intramol. aldol condensation.

There is still a lot of research devoted to this compound(SMILES：O=C(C1=CC=CO1)CC)Quality Control of 1-(Furan-2-yl)propan-1-one, and with the development of science, more effects of this compound(3194-15-8) can be discovered.

Name: 2-Mercapto-5-methylbenzimidazole. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 2-Mercapto-5-methylbenzimidazole, is researched, Molecular C8H8N2S, CAS is 27231-36-3, about Strong intra- and intermolecular aurophilic interactions in a new series of brilliantly luminescent dinuclear cationic and neutral Au(I) benzimidazolethiolate complexes. Author is Schneider, Jacob; Lee, Young-A.; Perez, Javier; Brennessel, William W.; Flaschenriem, Christine; Eisenberg, Richard.

The structural and photophys. properties of a new series of cationic and neutral Au(I) dinuclear compounds bridged by bis(diphenylphosphino)methane (dppm) and 5-X-substituted benzimidazolethiolate (X-BIT) ligands, where X = H (a), Me (b), OMe (c), and Cl (d), have been studied. Monocationic complexes [Au2(μ-X-BIT)(μ-dppm)](CF3CO2) (1) were prepared by the reaction of [Au2(μ-dppm)](CF3CO2)2 with 1 equiv of X-BIT in excellent yields. The cations 1a-1d possess similar mol. structures, each with a linear coordination geometry around the Au(I) nuclei, as well as relatively short intramol. Au(I)···Au(I) separations ranging between 2.88907(6) Å for 1d and 2.90607(16) Å for 1a indicative of strong aurophilic interactions. The cations are violet luminescent in CH2Cl2 solution with a λemmax of ca. 365 nm, assigned as ligand-based or metal-centered (MC) transitions. Three of the cationic complexes, 1a, 1b and 1d, exhibit unusual luminescence tribochromism in the solid-state, in which the photoemission is shifted significantly to higher energy upon gentle grinding of microcrystalline samples with ΔE = 1130 cm-1 for 1a, 670 cm-1 (1b), and 870 cm-1 (1d). The neutral dinuclear complexes [Au2(μ-X-BIT)(μ-dppm)] (2a-2d) were formed in good yields by the treatment of a CH2Cl2 solution of cationic compounds 1a-1d with NEt3. Complexes 2a-2d aggregate to form dimers having substantial intra- and intermol. aurophilic interactions with unsupported Au(I)···Au(I) intermol. distances in the range of 2.8793(4)-2.9822(8) Å, compared with intramol. bridge-supported separations of 2.8597(3)-2.9162(3) Å. Complexes 2a-2d exhibit brilliant luminescence in the solid-state and in DMSO solution with red-shifted λemmax energies in the range of 485-545 nm that are dependent on X-BIT and assigned as ligand-to-metal-metal charge transfer (LMCT) states based in part on the extended Au···Au interactions.

There is still a lot of research devoted to this compound(SMILES：SC1=NC2=CC(C)=CC=C2N1)Name: 2-Mercapto-5-methylbenzimidazole, and with the development of science, more effects of this compound(27231-36-3) can be discovered.

COA of Formula: C8H8N2S. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2-Mercapto-5-methylbenzimidazole, is researched, Molecular C8H8N2S, CAS is 27231-36-3, about New accelerator-cum-antioxidants for chloroprene rubber. Author is Khanra, Tapan Kumar; Maiti, Sukumar; Adhikari, Basudam.

2-Mercaptoimidazole (MI), N-methyl-2-mercaptoimidazole (MMI), 2-mercaptobenzimidazole (MBI), 5-methyl-2-mercaptobenzimidazole (MMBI) and 5-nitro-2-mercaptobenzimidazole (NMBI) have been tried as the crosslinking agent for chloroprene rubber (Neoprene W). Apart from the curing ability, these imidazole derivatives have also shown antioxidant properties. 1-(N-oxydiethylene thiocarbamyl)-2-(N-oxydiethylene thio)benzimidazole (MBSPT), a novel dual function accelerator-cum-antioxidant for diene rubbers, has also been used in Neoprene W. The cure characteristics, phys. properties of the vulcanizates and their aging behavior of stocks containing these imidazole derivatives, ethylene thiourea (Na-22) and MBSPT have been compared. Some of the compounds viz. MBSPT, MBI and MI may be prescribed as secondary accelerator-cum-antioxidants with some primary accelerator for filled neoprene rubber.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Pyrolysis of carbohydrates. Analysis of industrial caramel vapors, published in 1989-08-31, which mentions a compound: 3194-15-8, mainly applied to carbohydrate caramelization gas composition; glucose pyrolysis gas composition; sucrose pyrolysis gas composition, Safety of 1-(Furan-2-yl)propan-1-one.

Twenty nine compounds were identified by gas chromatog./mass spectrometry in the gaseous products from pyrolysis of glucose and sucrose under conditions of caramel manufacture The main product was 5-hydroxymethylfurfural (70-90%, depending on pyrolysis conditions). The compound was formed more easily from sucrose than from glucose, and its yield increased with increasing pyrolysis temperature Aliphatic and keto acids, heterocyclic compounds with furan or pyran ring, aromatic compounds, and bisfuran compounds were formed in minor amounts

There is still a lot of research devoted to this compound(SMILES：O=C(C1=CC=CO1)CC)Safety of 1-(Furan-2-yl)propan-1-one, and with the development of science, more effects of this compound(3194-15-8) can be discovered.
