6214-21-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6214-21-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,1 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6214-21:
(6*6)+(5*2)+(4*1)+(3*4)+(2*2)+(1*1)=67
67 % 10 = 7
So 6214-21-7 is a valid CAS Registry Number.

Nitration of deactivated aromatic compounds via mechanochemical reaction

Wu, Jian-Wei,Zhang, Pu,Guo, Zhi-Xin

supporting information, (2021/05/05)

A variety of deactivated arenes were nitrated to their corresponding nitro derivatives in excellent yields under high-speed ball milling condition using Fe(NO3)3·9H2O/P2O5 as nitrating reagent. A radical involved mechanism was proposed for this facial, eco-friendly, safe, and effective nitration reaction.

The Hammett equation applied to the nucleophilic displacement of ions and ion pairs on substituted benzenesulphonates

Alunni, Sergio,Pica, Monica,Reichenbach, Gustavo

, p. 265 - 270 (2007/10/03)

Nucleophilic substitution on meta- and para-substituted methyl benzenesulphonates was studied with two chloride salts with different structures: NBu4Cl or KCl-Kryptofix 2,2,2. Treating the results with the Acree equation shows that the reaction proceeds by two reaction paths, one involving the chloride ion and the other, slower one, involving the ion pairs. Treating the results with the Hammett equation gives consistent data, and shows that ρ is positive and nearly the same for the two reaction paths (ρ ≈ +2). The reactivity of methyl p-nitrobenzenesulphonate was compared with that of the corresponding ethyl derivative, and it is shown that the methyl derivative reacts faster than the ethyl derivative in both paths. The results are interpreted based on the assumption that in both paths a negative charge is developed on the leaving group in the transition state, and that the activated complex is linear.

Perchlorate Esters. Part 3. Correlation of the Rates of Reaction of Arenesulphonate Ions with Methyl Perchlorate in Acetonitrile

Kevill, Dennis N.,Lin, Gloria Meichia L.,Bahari, Mohd S.

, p. 49 - 52 (2007/10/02)

Second-order rate coefficients for the reactions of acetonitrile solutions of tetra-n-butylammonium benzensulphonate and seven meta- and para-substituted derivatives with methyl perchlorate, at 0.3 deg C lead to a Hammet ρ value (-1.10 +/- 0.04) essentially identical to those previously reported for reactions with other powerful methylating agents.When silver ion is substituted for tetra-n-butylammonium ion, the second-oreder rate coefficients become concetration dependent and the fall of with increasing salt concetration can be rationalised on the basis of only free anions being reactive.The calculated degrees of dissociation are applied tothe previously studied silver0ion assisted reaction of silver toluene-p-sulphonate with methyl iodide.
