The presence of the bromine and sulfonyl groups makes this compound a versatile reagent for various chemical reactions and applications.

Check Digit Verification of cas no

The CAS Registry Mumber 834-67-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 834-67:
(5*8)+(4*3)+(3*4)+(2*6)+(1*7)=83
83 % 10 = 3
So 834-67-3 is a valid CAS Registry Number.

S(vi) in three-component sulfonamide synthesis: Use of sulfuric chloride as a linchpin in palladium-catalyzed Suzuki-Miyaura coupling

Wang, Xuefeng,Yang, Min,Ye, Shengqing,Kuang, Yunyan,Wu, Jie

, p. 6437 - 6441 (2021/05/19)

Sulfuric chloride is used as the source of the -SO2- group in a palladium-catalyzed three-component synthesis of sulfonamides. Suzuki-Miyaura coupling between the in situ generated sulfamoyl chlorides and boronic acids gives rise to diverse sulfonamides in moderate to high yields with excellent reaction selectivity. Although this transformation is not workable for primary amines or anilines, the results show high functional group tolerance. With the solving of the desulfonylation problem and utilization of cheap and easily accessible sulfuric chloride as the source of sulfur dioxide, redox-neutral three-component synthesis of sulfonamides is first achieved.

Nickel-Catalyzed Decarboxylative Cross-Coupling of Bicyclo[1.1.1]pentyl Radicals Enabled by Electron Donor-Acceptor Complex Photoactivation

Polites, Viktor C.,Badir, Shorouk O.,Keess, Sebastian,Jolit, Anais,Molander, Gary A.

supporting information, p. 4828 - 4833 (2021/06/30)

The use of bicyclo[1.1.1]pentanes (BCPs) as para-disubstituted aryl bioisosteres has gained considerable momentum in drug development programs. Carbon-carbon bond formation via transition-metal-mediated cross-coupling represents an attractive strategy to generate BCP-aryl compounds for late-stage functionalization, but these typically require reactive organometallics to prepare BCP nucleophiles on demand from [1.1.1]propellane. In this study, the synthesis and Ni-catalyzed functionalization of BCP redox-active esters with (hetero)aryl bromides via the action of a photoactive electron donor-acceptor complex are reported.

AEROBIC OXIDATIVE SYNTHESIS OF SULFONAMIDE USING Cu CATALYST

Paragraph 0033-0037; 0039-0054; 0066-0069; 0151-0152, (2021/04/06)

The present invention relates to a method for oxidative synthesis of sulfonamides using copper catalysts. , Oxygen (O) is used. 2 The oxidative synthesis of sulfonamides (1) comprises reacting a 2 th or sulfonyl hydrazide primary amine with a sulfonyl hydrazide (sulfonamide) with a copper catalyst on a solvent under the conditions in which the sulphonamide is fed. The oxidation coupling of the present invention showed extensive substrate ranges in an amine comprising a 2 primary amine, 1 primary amine and amine hydrochloride salt. It is worth notable that non-reactive aliphatic sulfonyl hydrazides in previously reported anaerobic systems can be used for the aerobic oxidation coupling of the present invention. The oxidation coupling of the present invention has been more effective on large scale.
