115-85-5 Usage

Purification Methods

Purify it by vacuum distillation, percolate it through a column of alumina, then pass it through a packed column maintained by a countercurrent stream of N2 at reduced pressure [Dobry & Keller J Phys Chem 61 1448 1957].

Check Digit Verification of cas no

The CAS Registry Mumber 115-85-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 115-85:
(5*1)+(4*1)+(3*5)+(2*8)+(1*5)=45
45 % 10 = 5
So 115-85-5 is a valid CAS Registry Number.

Dependence of Transition-state Structure on Nucleophile in the Reaction of Aryl Oxide Anions with Aryl Diphenylphosphate Esters

Ba-Saif, Salem A.,Waring, Mark A.,Williams, Andrew

, p. 1653 - 1659 (2007/10/02)

Second-order rate constants have been measured for reaction of aryl oxide anions with substituted phenyl diphenylphosphate esters in aqueous media at 25 deg C.The rate constants obey good Broensted type correlations with the pKa of either the leaving group or nucleophile.Both βnuc and βlg values vary substantially with basicity of leaving group and nucleophile, respectively, providing evidence for coupling between bond fission and formation.Attack of phenolate ions on 2,4-dinitrophenyl diphenylphosphate has a βnuc value of 0.12 giving a Kreevoy's tightness parameter value, τ, of 0.18 which is consistent with an 'exploded' transition state for the identity reaction involving 2,4-dinitrophenolate ion as the nucleophile.Transfer of the diphenylphosphinoyl group between 2,4-dinitrophenolate ion nucleophiles has a τ value of 0.28, consistent with an 'exploded' transition state for this reaction also.The identity reaction involving transfer of the diphenylphosphoryl group between phenolates ions has a τ value of 1.20, indicating an almost synchronous process.The data for transfer of the diphenylphosphinoyl and diethylphosphoryl groups between phenolate ion nucleophiles indicates that the identity reaction for the parent phenol has an almost synchronous mechanism for the former phosphinoyl species (τ = 0.92) whereas the latter (τ = 1.45) is almost associative.
