COMPARATIVE-STUDY OF AROMATICITY IN 5-MEMBERED RINGS CONTAINING S, SO AND SO2 GROUPS
Owing to the importance of the concept of aromaticity, different indices have been developed to try to quantify this property. The possible pi-delocalization through an X-SOn-X group (X = C, N; n = 0, 1 or 2) could explain heteroaromaticity in rings containing the moiety. For that reason, the aromaticity of five-membered sulphur-containing rings with different oxidation numbers (S, SO and SO2) and including no (thiophene), one (isothiazole) or two (1,2,5-thiadiazole) adjacent atoms was investigated. Ab initio calculations were carried out to determine geometrical parameters (planarity of the ring, bond length and bond order), electronic structure (charge distribution and dipolar moment) and the participation of d-orbitals of sulphur. According to these calculations, only compounds with S(II) can be considered to be aromatic, whereas compounds bearing S(IV) or S(VI) are better described as ylides.
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 2051-95-8 is helpful to your research. Recommanded Product: 2051-95-8.
