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 Copper-catalyzed aminothiolation of terminal alkynes with tunable regioselectivity, published in 2019, which mentions a compound: 27231-36-3, mainly applied to thiazolobenzimidazole preparation regioselective; terminal alkyne regioselective cycloaddition mercaptobenzimidazole aminothiolation copper catalyst, Formula: C8H8N2S.

A simple, mild, and efficient copper(I)-catalyzed aminothiolation of terminal alkynes R1CCH (R1 = HOCH2CH2, Me3Si, cyclohexen-1-yl, Ph, pyridin-2-yl, etc.) with 5-R2-substituted 2-mercaptobenzimidazoles (R2 = H, Me, MeO, O2N) gave both 2- and 3-substituted thiazolo[3,2-a]benzimidazoles I, where complementary regioselectivities could be achieved by using sterically different phenanthroline-based ligands, such as 1,10-phenanthroline and 2,9-diisopropyl-1,10-phenanthroline.

《Copper-catalyzed aminothiolation of terminal alkynes with tunable regioselectivity》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(2-Mercapto-5-methylbenzimidazole)Formula: C8H8N2S.

Recommanded Product: 2-Mercapto-5-methylbenzimidazole. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 2-Mercapto-5-methylbenzimidazole, is researched, Molecular C8H8N2S, CAS is 27231-36-3, about Trans-1,2-bis(diphenylphosphino)ethene as bridging ligand in thione-S-ligated dimeric copper(I) chloride complexes. Author is Aslanidis, P.; Cox, P. J.; Divanidis, S.; Karagiannidis, P..

Several mixed-ligand complexes were prepared by treatment of Cu(I) chloride with equimolar amounts of trans-1,2-bis(diphenylphosphino)ethene (trans-dppen) in MeCN followed by the addition of a methanolic solution of one equivalent of a heterocyclic thione (L). The novel complex compounds were characterized by single-crystal x-ray diffraction, 1H NMR and IR spectroscopy as well as by elemental analyses and m.ps. The x-ray structures of three examples confirm that the compounds are homobimetallic dimers [CuCl(μ2-trans-dppen)(L)]2 containing two tetrahedral coordination units joined by two trans-dppen bridges.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 3194-15-8, is researched, SMILESS is O=C(C1=CC=CO1)CC, Molecular C7H8O2Journal, Monatsschrift fuer Brauwissenschaft called The use of oats in brewing, Author is Hanke, S.; Zarnkow, M.; Kreisz, S.; Back, W., the main research direction is oat beer brewing malting history.Related Products of 3194-15-8.

Oats (Avena sativa) are one of the most popular cereals for human consumption. In the middle ages oats were the brewing cereal par excellence. Over the centuries they were substituted by other cereals and their brewing properties were nearly forgotten. Today oats are popular once more because of their excellent health-related properties. For people who suffer with celiac disease oats are also of interest. Based on their historical use in brewing and their health-related properties pilot malting trials were carried out with different varieties, followed by brewing trials with a selected variety. The results obtained showed that oat malt is an appropriate choice for brewing.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called An environmentally benign procedure for the synthesis of substituted 2-thiobenzothiazoles, 2-thiobenzoxazoles, 2-thiobenzimidazoles, and 1,3-oxazolopyridine-2-thiols, published in 2011-09-30, which mentions a compound: 27231-36-3, Name is 2-Mercapto-5-methylbenzimidazole, Molecular C8H8N2S, SDS of cas: 27231-36-3.
