79419-73-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 79419-73-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,4,1 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 79419-73:
(7*7)+(6*9)+(5*4)+(4*1)+(3*9)+(2*7)+(1*3)=171
171 % 10 = 1
So 79419-73-1 is a valid CAS Registry Number.

Electrochemical Rearrangement of 3-Hydroxyoxindoles into Benzoxazinones

Vayer, Marie,Pastor, Miryam,Kofink, Christiane,Maulide, Nuno

supporting information, p. 27 - 32 (2022/01/15)

We report an unexpected rearrangement of 3-hydroxyoxindoles into benzoxazinones using electrochemistry. Our reaction employs mild and environmentally friendly conditions, and the benzoxazinone products are obtained in moderate to excellent yields. Mechanistic experiments suggest that a peroxide intermediate is likely involved.

Counterion Control of t-BuO-Mediated Single Electron Transfer to Nitrostilbenes to Construct N-Hydroxyindoles or Oxindoles

Driver, Tom G.,Sung, Siyoung,Wink, Donald J.,Zadrozny, Joseph M.,Zhao, Yingwei,Zhu, Haoran

supporting information, p. 19207 - 19213 (2021/08/09)

tert-Butoxide unlocks new reactivity patterns embedded in nitroarenes. Exposure of nitrostilbenes to sodium tert-butoxide was found to produce N-hydroxyindoles at room temperature without an additive. Changing the counterion to potassium changed the reaction outcome to yield solely oxindoles through an unprecedented dioxygen-transfer reaction followed by a 1,2-phenyl migration. Mechanistic experiments established that these reactions proceed via radical intermediates and suggest that counterion coordination controls whether an oxindole or N-hydroxyindole product is formed.

Asymmetric organocatalytic α-amination of 2-oxindoles with bis(2,2,2-trichloroethyl)azo-dicarboxylate

Bondanza, Mattia,Pescitelli, Gennaro,Mandoli, Alessandro

supporting information, p. 2590 - 2594 (2018/05/29)

An enantioselective electrophilic amination of 3-substituted-2-oxindoles is reported, using bis(2,2,2-trichloroethyl)azo-dicarboxylate and commercially available Cinchona alkaloid organocatalysts. The best results were obtained in the reaction of 3-aryl s
