84224-69-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84224-69-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,2 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84224-69:
(7*8)+(6*4)+(5*2)+(4*2)+(3*4)+(2*6)+(1*9)=131
131 % 10 = 1
So 84224-69-1 is a valid CAS Registry Number.

AlCl3-Catalyzed Intermolecular Annulation of Thiol Derivatives and Alkynes by 1,2-Sulfur Migration: Construction of 6-Substituted Benzo[b]thiophenes

Ramesh,Guntreddi, Tirumaleswararao,Sahoo, Akhila K.

, p. 4405 - 4413 (2017/08/23)

A method for the AlCl3-catalyzed intermolecular oxidative annulation of N-(arylthio)phthalimide derivatives with alkynes has been developed. The annulation reaction occurs at room temperature and involves the oxidative cleavage of the S–N bond and 1,2-sulfur migration, which leads to the construction of diverse arrays of π-conjugated 6-substituted 2,3-diarylbenzo[b]thiophene derivatives.

Synthesis and Reactions of Sulfenic Trifluoromethanesulfonic Anhydrides

Effenberger, Franz,Russ, Werner

, p. 3719 - 3736 (2007/10/02)

Sulfenyl halogenides 1 and 4 react with silver trifluoromethanesulfonate (2) to give aryl 3 and alkylsulfenic trifluoromethanesulfonic anhydrides 5, resp., in good yields; 3 and 5 could not be isolated because of their instability. 1H NMR spectroscopic data of 5a, b, each in dichloromethane and nitromethane, resp., are indicative of a dissoziation to adducts of alkylsulfenylium ions and the solvent.Whereas 3 do not react with aromatic compounds, addition products with diphenylacetylene, arylsulfenylvinyl trifluoromethanesulfonates 11, are formed smoothly, which under the reaction conditions immediately cyclize to give benzothiophenes 10 in excellent yields.
