117296-15-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 117296-15-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,2,9 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117296-15:
(8*1)+(7*1)+(6*7)+(5*2)+(4*9)+(3*6)+(2*1)+(1*5)=128
128 % 10 = 8
So 117296-15-8 is a valid CAS Registry Number.

Substrate-Controlled Selectivity Switch in the Three-Component Coupling Involving Arynes, Aromatic Tertiary Amines, and CO2

Bhojgude, Sachin Suresh,Roy, Tony,Gonnade, Rajesh G.,Biju, Akkattu T.

, p. 5424 - 5427 (2016/11/04)

The transition-metal-free multicomponent coupling involving arynes, aromatic tertiary amines, and CO2 is reported. The reaction exhibits switchable selectivity depending on the electronic nature of the aromatic amines used. With amines bearing electron-releasing/neutral groups as the nucleophilic trigger, the reaction afforded 2-arylamino benzoates via a nitrogen to oxygen alkyl group migration. Employing electron-deficient amines in the reaction furnished 2-aminoaryl benzoates proceeding via the aryl to aryl amino group migration resembling a Smiles rearrangement.

Sc(OTf)3-catalyzed dehydrogenative cyclization for synthesis of N-methylacridones

Li, Xi-An,Wang, Hong-Li,Yang, Shang-Dong

, p. 1794 - 1797 (2013/05/23)

A novel method has been developed for the synthesis of substituted N-methylacridones from 2-(N-methyl-N-phenylamino)benzaldehydes via dehydrogenative cyclization. This transformation involves two primary processes: the aldehyde first coordinates with Sc(OTf)3 and induces the aromatic electrophilic substitution (SEAr) reaction to form the active intermediate N-methyl-acridin-9-ol, which is then quickly oxidized in situ to afford the acridones. Furthermore, the procedure involved is both environmental friendly and atom efficient; H2O is the only byproduct in this reaction.
