General Description

Thietane-1,1-dioxide, also known as tetrahydrothiophene 1,1-dioxide, is a chemical compound with the formula C4H8O2S. It is a heterocyclic organic compound containing a four-membered ring with one oxygen and one sulfur atom. Thietane-1,1-dioxide is a colorless, flammable liquid with a boiling point of 98-100°C. It is primarily used as a solvent and a starting material in the synthesis of other organic compounds. Thietane-1,1-dioxide has also been studied for its potential applications in pharmaceuticals and agrochemicals. Due to its ring strain and unique structural properties, thietane-1,1-dioxide is of interest in the field of organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 5687-92-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,8 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5687-92:
(6*5)+(5*6)+(4*8)+(3*7)+(2*9)+(1*2)=133
133 % 10 = 3
So 5687-92-3 is a valid CAS Registry Number.

Observed and calculated 1Hand 13C chemical shifts induced by the in situ oxidation ofmodel sulfides to sulfoxides and sulfones

Dracinsky, Martin,Pohl, Radek,Slavetinska, Lenka,Budesinsky, Milos

experimental part, p. 718 - 726 (2011/05/15)

A series of model sulfides was oxidized in the NMR sample tube to sulfoxides and sulfones by the stepwise addition of meta-chloroperbenzoic acid in deuterochloroform. Various methods of quantum chemical calculations have been tested to reproduce the observed 1H and 13C chemical shifts of the starting sulfides and their oxidation products. It has been shown that the determination of the energy-minimized conformation is a very important condition for obtaining realistic data in the subsequent calculation of the NMR chemical shifts. The correlation between calculated and observed chemical shifts is very good for carbon atoms (even for the 'cheap' DFT B3LYP/6-31G* method) and somewhat less satisfactory for hydrogen atoms. The calculated chemical shifts induced by oxidation (the δd values) agree even better with the experimental values and can also be used to determine the oxidation state of the sulfur atom (-S-, -SO-, -SO2 -).
