89170-76-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89170-76-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,7 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89170-76:
(7*8)+(6*9)+(5*1)+(4*7)+(3*0)+(2*7)+(1*6)=163
163 % 10 = 3
So 89170-76-3 is a valid CAS Registry Number.

Regioselective Synthesis of 2° Amides Using Visible-Light-Induced Photoredox-Catalyzed Nonaqueous Oxidative C-N Cleavage of N, N-Dibenzylanilines

Neerathilingam, Nalladhambi,Bhargava Reddy, Mandapati,Anandhan, Ramasamy

supporting information, p. 15117 - 15127 (2021/10/25)

A visible-light-driven photoredox-catalyzed nonaqueous oxidative C-N cleavage of N,N-dibenzylanilines to 2° amides is reported. Further, we have applied this protocol on 2-(dibenzylamino)benzamide to afford quinazolinones with (NH4)2S2O8 as an additive. Mechanistic studies imply that the reaction might undergo in situ generation of α-amino radical to imine by C-N bond cleavage followed by the addition of superoxide ion to form amides.

Selective catalytic Hofmann: N -alkylation of poor nucleophilic amines and amides with catalytic amounts of alkyl halides

Xu, Qing,Xie, Huamei,Zhang, Er-Lei,Ma, Xiantao,Chen, Jianhui,Yu, Xiao-Chun,Li, Huan

supporting information, p. 3940 - 3944 (2016/07/21)

Using only catalytic amounts of alkyl halides in the reactions of poor nucleophilic amines/amides and alcohols led to a selective Hofmann N-alkylation reaction catalytic in alkyl halides, providing a practical and efficient method for the practical synthesis of mono- or di-alkylated amines/amides in high selectivities. This new method avoids the use of large amounts of bases, alkyl halides, and solvents, and generates water as the only byproduct. Preliminary mechanistic studies showed that alkyl halides are key intermediates/catalysts regeneratable in the reaction cycle.

Copper-catalyzed electrophilic amination of arylsilanes with hydroxylamines

Miki, Yuya,Hirano, Koji,Satoh, Tetsuya,Miura, Masahiro

supporting information, p. 172 - 175 (2013/03/28)

A copper-catalyzed electrophilic amination of aryl[(2-hydroxymethyl)phenyl] dimethylsilanes with O-acylated hydroxylamines has been developed to afford the corresponding anilines in good yields. The catalytic reaction proceeds very smoothly under mild conditions and tolerates a wide range of functional groups.
