55681-26-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55681-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,6,8 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55681-26:
(7*5)+(6*5)+(5*6)+(4*8)+(3*1)+(2*2)+(1*6)=140
140 % 10 = 0
So 55681-26-0 is a valid CAS Registry Number.

Aqueous α-Arylation of Mono- and Diarylethanone Enolates at Low Catalyst Loading

Astarloa, Iratxe,SanMartin, Raul,Herrero, María Teresa,Domínguez, Esther

supporting information, p. 1711 - 1718 (2018/03/21)

Acetophenone and deoxybenzoin derivatives are selectively α-arylated using a combination of very small amounts of palladium acetate and diphenylphosphine oxide as catalyst system and water as the only solvent. Target di- and triarylethanones are isolated virtually free of metal residues, and the reaction is amenable to gram-scale. A mechanistic proposal based on TEM images, poisoning experiments, kinetic plot and ESI-MS spectrometry is also provided. (Figure presented.).

One-pot synthesis of diarylmethanones through palladium-catalyzed sequential coupling and aerobic oxidation of aryl bromides with acetophenone as a latent carbonyl donor

Wang, Xing,Liu, Fu-Di,Tu, Hai-Yang,Zhang, Ai-Dong

, p. 6554 - 6562 (2014/08/05)

A one-pot palladium-catalyzed synthesis of symmetrical and unsymmetrical diarylmethanones using acetophenone and aryl bromides as raw materials has been developed. In this reaction, acetophenone acts as a latent carbonyl donor and two pathways of palladium-catalyzed sequential coupling and aerobic oxidation are identified. The reaction is applicable to a spectrum of substrates and delivers the products in moderate to good yields. This method can be used for the synthesis of ketoprofen, a nonsteroidal anti-inflammatory drug, in a two-step procedure and 45% overall yield.

Lewis acid-promoted friedel-crafts alkylation reactions with α-ketophosphate electrophiles

Smith, Austin G.,Johnson, Jeffrey S.

supporting information; experimental part, p. 1784 - 1787 (2010/09/05)

The BF3·OEt2-promoted nucleophilic substitution of α-aryl-α-ketophosphates to afford α,α-diaryl ketone products is described. Electron-rich α-ketophosphates perform best, with electron-neutral and electron-poor substrates also tolerated. The reaction is tolerant of a range of aromatic, heteroaromatic, and nonaromatic nucleophiles, with yields ranging from 44% to 84%. Enantioenriched starting material yields racemic product, suggesting an SN1 pathway via an acylcarbenium ion.
