85963-94-6

Triphenylverdazylium p-toluenesulfonate is a complex organic compound with the chemical formula C23H22N3+.C7H7O3S-. It is a derivative of triphenylverdazylium, a highly reactive and unstable compound, and p-toluenesulfonate, a common organic salt. triphenylverdazylium p-toluenesulfonate is characterized by its deep red color and is often used as a reagent in organic synthesis, particularly in the preparation of various dyes and pigments. Due to its sensitivity to light and moisture, it is typically stored under controlled conditions to maintain its stability. Triphenylverdazylium p-toluenesulfonate is also known for its potential applications in the development of new materials and pharmaceuticals, although its use is limited by its reactivity and the challenges associated with handling such a sensitive compound.

85963-94-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 85963-94-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,9,6 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 85963-94:
(7*8)+(6*5)+(5*9)+(4*6)+(3*3)+(2*9)+(1*4)=186
186 % 10 = 6
So 85963-94-6 is a valid CAS Registry Number.

cd title: ADAMANTANE BRIGDEHEAD DERIVATIVES.The kinetics of the heterolysis of 1-adamantyl p-toluenesulfonate were investigated in δ-butyrolactone, propylene carbonate, and acetonitrile in the presence of triphenylverdazyls as internal indicators, v = k.It was concluded that the verdazyls and chlorides always react with the solvent-separated ion pair of the substrate, while the bromides react with the sterically separated ion pair in one case and with the solvent-separated ion pair in the other.A comparative analysis was made of the salt and solvation effects in the heterolysis of 1-adamantyl p-toluenesulfonate, 1-adamantyl chloroformate, and 1-adamantyl iodide.The reaction mechanism is discussed.

KINETICS AND MECHANISM OF MONOMOLECULAR HETEROLYSIS OF FRAMEWORK COMPOUNDS. I. IONIZATION OF 1-ADAMANTYL p-TOLUENESULFONATE IN ACETONITRILE

The heterolysis of 1-adamantyl p-toluenesulfonate in acetonitrile was investigated preparatively and kinetically (in the presence of triphenylverdazyl as internal indicator) ( v = k, k25 = 1.97E-6 sec-1, ΔH = 88.8 kJ/mole, ΔS25 = -57.3 J/mole*deg).Additions of tetraethylammonium bromide, tetraethylammonium perchlorate, tetraethylammonium p-toluenesulfonate, and N-butylquinolinium p-toluenesulfonate ( 0.05 - 0.005 M ) do not affect the reaction rate, and the normal salt effect and the effect of the law of mass action do not appear.The reaction rate is increased a little by the addition of water and phenol, and is increased greatly by the addition of sodium perchlorate, lithium perchlorate, and lithium bromide.The salt effect increases with decrease in the size of the cation ( electrophilic catalysis ).The addition of the cation was confirmed by additions of dibenzo-18-crown-6.It is suggested that the controlling stage of the reaction involves conversion of an intimate ion pair of the substrate into a solvent-separated ion pair.
