Chemical Research Letters, April 2021. Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 2307-69-9, Name is Isopropyl 4-methylbenzenesulfonate, molecular formula is C10H14O3S, Related Products of 2307-69-9, belongs to isothiazole compound, is a common compound. In a patnet, author is Szabo, D, once mentioned the new application about 2307-69-9.
Two cyclic acylaminochloro-lambda(4)-sulfanes containing a five- or a six-membered hetero ring (5 and 6), as well as their cyclic acylaminosulfonium salt analogues without (7 and 8) and with S … O close contact (9 and 10), have been prepared and their molecular structures determined by X-ray diffraction. Compounds 5, 6, 9 and 10 exhibit a trigonal bipyramidal configuration about the central sulfur atom, with nitrogen and chlorine (in 5 and 6) or with nitrogen and oxygen atoms (in 9 and 10) in axial positions. In sulfonium salts 7 and 8, the bond angles about sulfur an similar to those obtained for analogous lambda(4)-sulfanes 5 and 6. The interatomic S-N distances, which range from 1.66 to 1.73 Angstrom, point to a strong covalent bond in an compounds investigated. In lambda(4)-sulfanes the axial S-Cl hypervalent bond (2.69 Angstrom in 5, 3.10 Angstrom in 6) is rather long and markedly polarized. In methoxycarbonyl-substituted acylaminosulfonium salts the interatomic S … O distances are 2.41 Angstrom (in 9) and 2.74 Angstrom (in 10). The individual S-N, S-Cl, S … O and S-C-ar bond lengths, as well as the N(ax)-S-X(ax) (X = Cl or O=), N(ax)-S-C-ar(eq), Cl(ax)-S-C-ar(eq) and C-ar(eq)-S-C-ar'(eq) bond angles (159-176 degrees, 90-104 degrees, 85-96 degrees and 101-104 degrees, respectively), which depend on both the axial substituents on sulfur and the size of the hetero ring, are compared and discussed. The five-membered 2,3-dihydro-isothiazole rings in 5, 7 and 9 are practically planar, whereas the 1,2-oxathiole ring in 10 is unusually puckered. The six-membered dihydro-1,2-thiazine rings in 6, 8 and 10, as well as the 1,2-oxathiine ring in 9, assume a more or less inverted half-chair form. The orientations of the aromatic rings in relation to the C-ar(eq)-S-C-ar'(eq) plane are also discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
