654-60-4 Usage
Type of Compound
Dithiin derivative
Explanation
A dithiin is an organic compound containing two adjacent sulfur atoms and two adjacent carbon atoms in a cyclic structure. The compound in question is a derivative of dithiin, meaning it has been chemically modified.
Explanation
The dithiin ring has four trifluoromethyl groups (CF3) attached to it. This substitution significantly affects the compound's properties, making it highly electronegative and reactive.
Explanation
The presence of the tetrakis(trifluoromethyl) groups increases the electronegativity of the compound, making it more likely to attract electrons in chemical reactions.
Explanation
Due to its high electronegativity, the compound is highly reactive and can readily participate in various chemical reactions.
Explanation
The compound is used as a reagent in organic synthesis, particularly in the formation of carbon-carbon and carbon-sulfur bonds. Its strong electron-withdrawing nature also makes it suitable for use in certain types of chemical reactions and as a component in pharmaceuticals and materials science.
Explanation
The compound has a cyclic structure, with two sulfur atoms and two carbon atoms adjacent to each other, forming the dithiin ring.
Explanation
The four trifluoromethyl groups (CF3) are the functional groups attached to the dithiin ring, contributing to the compound's unique properties.

Check Digit Verification of cas no
The CAS Registry Mumber 654-60-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 654-60:
(5*6)+(4*5)+(3*4)+(2*6)+(1*0)=74
74 % 10 = 4
So 654-60-4 is a valid CAS Registry Number.

4,5-Bis(trifluoromethyl)-1,2,3-trithiolylium hexafluoroarsenate, which contains the 7? radical cation, the first example of a cationic carbon-sulfur heterocycle, has been prepared and characterised.It was prepared as a purple solid in 90 percent yield by the reaction of F3CCCCF3 with a 1:1 mixture of S4(AsF6)2 and S8(AsF6)2 in SO2 at 50 deg C for 2 weeks.Small amounts of a homopolyatomic sulfur cation (probably S82+) were removed by work-up with fresh F3CCCCF3 and AsF5 in SO2 at 50 deg C for 8d.The AsF6 was characterised in the solid state by chemical analyses, IR, mass spectrometry and X-ray crystallography.The crystal structure consists of layers containing both monomeric, planar radical cations and AsF6- anions .A powder photograph of the bulk product correlated with the single-crystal data, and a variable-temperature magnetic susceptibility study indicated that AsF6 is a paramagnetic solid, exhibiting oridinary Curie-Weiss behaviour, μ = 1.68, Θ = -0.6 K (μ = 2.1 in SO2 solution at room temperature).The ESR spectrum of in SO2 is identical to that previously reported for , which suggested that spectra long assigned to 1,2-dithiete cations are in fact due to 1,2,3-trithiolium cations.This is supported by the ESR spectrum of , which consisted of a singlet at g = 2.017, with two sets of 33S satellites in a 2:1 intensity ratio, with very similar 33S coupling constants (8.0 and 8.9 G).The salt AsF6 is reduced by KI to give a mixture of neutral cyclic polysulfides including (43percent) and the previously unknown (23percent).Attempts to oxidise with AsF5 were unsuccessful.
