Ab initio HF, density functional and experimental studies on the IR spectra and structure of 1,2-benzisothiazol-3-(2H)-thione-1,1-dioxide (thiosacchanin) and its nitranion

The spectral and structural changes taking place in the course of the conversion of 1,2-benzisothiazol-3-(2H)-thione-1,1-dioxide (thiosaccharin) into a nitranion have been studied on the basis of both IR spectra and ab initio HF 6-31G(d) and BLYP 6-31G(d,p) force field calculations. The conversion causes nuSO(2)as and nuSO(2)s frequency decreases of 47 and 13 cm-1, respectively, and other spectral changes. The nuC double bond S coordinate is strongly delocalized. The ab initio geometries of the isolated molecule and nitranion agree well with the single-crystal X-ray ones, determined for thiosaccharin and its sodium (potassium) monohydrate salts, respectively. The nitranionic charge is delocalized almost uniformly within the thiocarbonyl (0.29 e-), sulfonyl (0.24 e-), and phenylene (0.24 e-) groups, and the nitranionic center (0.23 e-).

THE N-H STRETCHING REGION OF SOME IMIDES AND THIOIMIDES

The multiplet structure of nuN-H and nuN-D bands of solid phthalimide, monothiophthalimide, dithiophthalimide, isatin, saccharin and of their deuterated analogues has been explained as being a result of Fermi resonance of the fundamentals of nuN-H ans nuN-D with combinations and/or overtones.The submaxima of 3080 and 2970 cm-1 of saccharin as well as pronounced doublet at 2465 and 2345 cm-1 of d-phthalimide move to lower frequency in the low temperature ir spectra, while the “windows” remain fixed at 3045 and 2380 cm-1, respectively.These examples could be a striking demonstration of Evans type Fermi resonance.

27148-03-4, Name is Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide, belongs to isothiazole compound, is a common compound. 27148-03-4In an article, authors is Al-Jibori, Subhi A., once mentioned the new application about 27148-03-4.

A comparative study of the coordination of saccharinate, thiosaccharinate and benzisothiozolinate ligands to cyclometalated [Pd(Me2NCH2C6H4-kappa2N,C)(mu-Cl)]2: Molecular structures of [Pd(Me2NCH2C6H4-kappa2N,C)(mu-X)]2 (X?=?sac, bit and tsac) and [Pd(Me2NCH2C6H4-kappa2N,C)Cl(ampyH-kappa1N)] (ampyH?=?2-amino-3-methylpyridine)

Reactions of [Pd(Me2NCH2C6H4-kappa2N,C)(mu-Cl)]2 with two equivalents of sodium saccharinate (Nasac), thiosaccharin (Htsac) or sodium benzisothiozolinate (Nabit) results in the stepwise substitution of the bridging halides to form sequentially [Pd2(Me2NCH2C6H4-kappa2N,C)2(mu-Cl)(mu-X)] (X = sac, tsac) and [Pd(Me2NCH2C6H4-kappa2N,C)(mu-X)]2 (X = sac, tsac, bit). The molecular structures of all three disubstituted complexes are reported. In each the two metalated ligands bind in a chelate manner adopting a relative anti conformation, while the new ligands bridge the two palladium atoms adopting a relative cis conformation. The local conformation about each palladium differs with small ligand changes. Thus in the sac and bit complexes all nitrogens lie trans to one another, in the tsac complex they are cis. Conformational changes also lead to large differences in the non-bonded Pd?Pd distance which range over 0.5 A. Treatment of [Pd(Me2NCH2C6H4-kappa2N,C)(mu-Cl)]2 with two equivalents of 2-amino-3-methylpyridine (ampyH) in the presence of NEt3 affords mononuclear [PdCl(Me2NCH2C6H4-kappa2N,C)(ampyH-kappa1N)] as a result of ?bridge-splitting?, the ampyH ligand binding through the pyridyl-nitrogen and lying approximately perpendicular to the PdCClN2 plane as shown by a crystallographic study.
