General Description

Phenyltetramethylenesulfonium hexafluorophosphate is a compound with the chemical formula (C6H5)(CH2)4S+PF6-. It is a quaternary ammonium salt containing a sulfonium group and a hexafluorophosphate anion. PHENYLTETRAMETHYLENESULFONIUM HEXAFLUOROPHOSPHATE is commonly used as a phase-transfer catalyst in organic synthesis and can facilitate the transfer of a reactant from one phase to another, such as from an organic solvent to an aqueous phase. It is also known for its high thermal stability and solubility in a wide range of organic solvents. Additionally, it has been studied for its potential application in electrochemical devices and as a stabilizer in polymers.

Check Digit Verification of cas no

The CAS Registry Mumber 82135-88-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,3 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 82135-88:
(7*8)+(6*2)+(5*1)+(4*3)+(3*5)+(2*8)+(1*8)=124
124 % 10 = 4
So 82135-88-4 is a valid CAS Registry Number.

One-Electron Chemical Reductions of Phenylalkylsulfonium Salts

Beak, Peter,Sullivan, Thomas A.

, p. 4450 - 4457 (2007/10/02)

Twenty-two arylalkylsulfonium salts have been reduced with potassium in graphite in tetrahydrofuran and the sulfide products identified.Two trialkylsulfonium salts did not reduce under these conditions.Comparison of the sulfides from a series of monophenylalkylsulfonium salts reveals a leaving-group propensity of benzyl > secondary > primary > methyl > phenyl in a ratio of 28:(6.0 +/- 0.3):1.0:(0.53 +/- 0.09): 0.05.The cleavage ratio is shown to be independent of the electron source and the homogeneity of heterogeneity of the reaction in two cases.Multiplicative transitivity of the above ratios is not observed, although the same qualitative order is found for other comparisons.These results are interpreted in terms of the initial formation of a ?-ligand radical anion sulfonium cation, which undergoes cleavage to a carbon radical and a sulfide.This appears to be the first evidence for this type of structure in a sulfur system.Leaving-group propensities different from the above order are observed in reductions of diphenylsulfonium and benzo-fused sulfonium salts, and rationales are offered.The intermediates in these reactions appear to be different from those involved in radical additions to, or displacements on, sulfur.
