683739-37-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 683739-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,3,7,3 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 683739-37:
(8*6)+(7*8)+(6*3)+(5*7)+(4*3)+(3*9)+(2*3)+(1*7)=209
209 % 10 = 9
So 683739-37-9 is a valid CAS Registry Number.

Copper-Catalyzed Aminoarylation of Alkenes via Aminyl Radical Addition and Aryl Migration

Wang, Jin-Lin,Liu, Mei-Ling,Zou, Jian-Yu,Sun, Wen-Hui,Liu, Xue-Yuan

supporting information, p. 309 - 313 (2022/01/04)

We describe a new strategy for aminoarylation of alkenes by copper-catalyzed smiles rearrangement using O-benzoylhydroxylamines as the amine reagent. This method affords various β-amino amide derivatives possessing a quaternary carbon center with wide functional group tolerance and high regioselectivity. The mechanistic studies indicate that the transformation can involve aminyl radical intermediates under acid-free condition.

O-cyclopropyl benzenesulfonyl aniline and preparation method thereof

-

Paragraph 0010-0013; 0018-0021, (2020/05/01)

The invention discloses an o-cyclopropyl benzenesulfonyl aniline and a preparation method thereof. The preparation method comprises the steps: dissolving 2-bromobenzenesulfonic acid and aniline in pyridine, then adding a condensing agent EDC-HCl, and carrying out a reaction for 2 to 4 h at a temperature of 60 to 80 DEG C so as to obtain 2-bromo-N-phenylbenzenesulfonamide; dissolving 2-bromo-N-phenylbenzenesulfonamide into a dioxane solution; adding cyclopropylboronic acid, sodium carbonate, an aqueous solution, Pd(dppf)Cl2 and a mixed system, carrying out a reaction at a temperature of 110 DEGC for 8-10 h in a nitrogen atmosphere, and carrying out after-treatment to obtain o-cyclopropyl benzenesulfonyl aniline. The synthesis route disclosed by the invention is short, only two-step reaction is carried out, and the reaction is easy to operate; the used preparation method is strong in operability and high in yield, and is an excellent method suitable for large-scale preparation. Becausethe compounds are valuable drug intermediates, the o-cyclopropyl benzenesulfonyl aniline has important research and practical values.

Cyclic Hypervalent Iodine Reagents for Azidation: Safer Reagents and Photoredox-Catalyzed Ring Expansion

Alazet, Sebastien,Preindl, Johannes,Simonet-Davin, Raphael,Nicolai, Stefano,Nanchen, Annik,Meyer, Thierry,Waser, Jerome

supporting information, p. 12334 - 12356 (2018/09/27)

Azides are building blocks of increasing importance in synthetic chemistry, chemical biology, and materials science. Azidobenziodoxolone (ABX, Zhdankin reagent) is a valuable azide source, but its safety profile has not been thoroughly established. Herein, we report a safety study of ABX, which shows its hazardous nature. We introduce two derivatives, tBu-ABX and ABZ (azidobenziodazolone), with a better safety profile, and use them in established photoredox- and metal-mediated azidations, and in a new ring-expansion of silylated cyclobutanols to give azidated cyclopentanones.
