Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.66-27-3, Name is Methyl methanesulfonate, SMILES is CS(=O)(OC)=O, belongs to thiazines compound. In a document, author is Yennawar, Hemant P., introduce the new discover, Recommanded Product: Methyl methanesulfonate.
Crystal structures of two solvated 2-aryl-3-phenyl-2,3-dihydro-4H-pyrido[3,2-e][1,3]thiazin-4-ones
The synthesis and crystal structures of 2-(4-fluorophenyl)-3-phenyl-2,3-dihydro-4H-pyrido [3,2-e] [1 ,3] thiazin-4-one toluene hemisolvate (1), C9H13FN2OS center dot- 0.5C(7)H(8), and 2-(4-nitrophenyl)-3-phenyl-2,3-dihydro-4H-pyrido [3,2-e] [1,3]thiazin-4-one isopropanol 0.25-solvate 0.0625-hydrate (2), C19H13N2O3S center dot- 0.25C(3)H(7)O center dot 0.0625H(2)O, are reported. Both are racemic mixtures (centrosymmetric crystal structures) of the individual compounds and incorporate solvent molecules in their structures. Compound 2 has four thiazine molecules in the asymmetric unit. All the thiazine rings in this study show an envelope pucker, with the C atom bearing the substituted phenyl ring displaced from the other atoms. The phenyl and aryl rings in each of the molecules are roughly orthogonal to each other, with dihedral angles of about 75 degrees. The extended structures of 1 and 2 are consolidated by C-H center dot center dot center dot O and C-H center dot center dot center dot N(pi), as well as T-type (C-H center dot center dot center dot pi) interactions. Parallel aromatic ring interactions pi-pi stacking) are observed only in 2.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 66-27-3 is helpful to your research. Recommanded Product: Methyl methanesulfonate.
