3058-46-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3058-46-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,5 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3058-46:
(6*3)+(5*0)+(4*5)+(3*8)+(2*4)+(1*6)=76
76 % 10 = 6
So 3058-46-6 is a valid CAS Registry Number.

Primary sulfonamide as a coupling partner: Copper(I)-catalyzed regioselective cross-coupling of 2-nitro benzenesulfonamides with thiol through the cleavage of Ar–SO2NH2 bonds

Chen, Junmin,Zhang, Kuo,Zhao, Yongli,Pu, Shouzhi

, p. 1316 - 1323 (2018/04/05)

In this article, we have presented a novel and efficient method for the direct synthesis of unsymmetrical sulfides through the copper(I)-catalyzed cross-coupling of 2-nitro benzenesulfonamides with thiols in the presence of catalytic amount of CuI in DMF as solvent at 100 °C. In addition, the products were obtained in high to excellent yields. More importantly, the novel system showed the primary 2-nitro benzenesulfonamides as a new coupling partner and regioselectively promoted C–S bond-forming transformations through the cleavage of Ar–SO2NH2 bonds.

Synthesis of aryl sulfides by decarboxylative C-S cross-couplings

Duan, Zhongyu,Ranjit, Sadananda,Zhang, Pengfei,Liu, Xiaogang

supporting information; experimental part, p. 3666 - 3669 (2009/12/07)

A study was conducted to demonstrate the transition-metal-catalyzed synthesis of aryl sulfides by decarboxylative C-S cross-couplings. Coupling reaction of 2-nitrobenzoic acid with 1-octanethiol were carried in the presence of different combinations of tr

149. Notizen zur Synthese von 2-Aminophenylsulfonen

Courtin, Alfred,Tobel, Hans-Rudolf von,Auerbach, Guenther

, p. 1412 - 1419 (2007/10/02)

Syntheses of the alkyl, cycloalkyl and aryl 2-aminophenyl sulfones 10 were achieved by oxidation of the corresponding 2-nitrophenyl sulfides 7 to the 2-nitrophenyl sulfones 9 followed by ethanolic Bechamp-reduction.The sulfides 7 in turn were obtained by either reactions of 2-nitro-thiophenol (8) with the appropriate alkyl and cycloalkyl halides or of 2-chloro-nitrobenzene (5) with the relevant thiols.Condensation of 2-nitrobenzenesulfinic acid (3) with bromoacetic acid in aqueous alkaline solution led - presumably via 2-nitrophenylsulfonylacetic acid (4) - to methyl2-nitrophenyl sulfone (1), reduction of which gave 2-aminophenyl methyl sulfone (2).Treatment of 2-aminothiophenol (11) with t-butyl alcohol in aqueous sulfuric acid gave 2-aminophenyl t-butyl sulfide (12), which was acetylated to o-t-butylthio-acetanilide (13).Oxidation of the latter to o-t-butylsulfonyl-acetanilide (14) followed by hydrolysis led to 2-aminophenyl t-butyl sulfone (15).
