(4-Methoxyphenyl)dimethylselenonium triflate is a chemical compound with the molecular formula C9H12F3O4Se. It is a colorless solid that is soluble in organic solvents. (4-methoxyphenyl)dimethylselenonium triflate is an organoselenium compound, which means it contains selenium in its structure. It is often used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and as a source of electrophilic selenium. The triflate group (CF3SO3-) in the compound makes it a good leaving group, facilitating reactions with nucleophiles. Its applications include the synthesis of various organic compounds and pharmaceuticals, as well as in the study of selenium-containing natural products.

Check Digit Verification of cas no

The CAS Registry Mumber 98652-07-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,5 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 98652-07:
(7*9)+(6*8)+(5*6)+(4*5)+(3*2)+(2*0)+(1*7)=174
174 % 10 = 4
So 98652-07-4 is a valid CAS Registry Number.

Methyl Transfers. 10. The Marcus Equation Application to Soft Nucleophiles

Lewis, Edward S.,McLaughlin, Mark L.,Douglas, Thomas A.

, p. 6668 - 6673 (2007/10/02)

The Marcus equation to methyl transfers is shown to cover reactions of " soft" nucleophiles, although small discrepancies occur.Rates and equilibria are reported for a series of reactions of arylmethylselenides with (p-chlorophenyl)dimethylselenonium ion.Experimental reaction rates between "hard" methylating agents and "soft" nucleophiles show small deviations from the calculated values, mostly but not always in the direction predicted by the HSAB principle.The Marcus equation fails to explain the previously reported "inversion" of reaction rates of 4-nitrothiophenoxide and of 4-nitrophenoxide with methyl iodide and dimethyl sulfate.Identity rates for dimethyl sulfate, methyl methanesulfonate (using 3He), methyl iodide (using 125I), and methyl triflate (using 35S) in sulfolane are reported.
