51431-52-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51431-52-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,4,3 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 51431-52:
(7*5)+(6*1)+(5*4)+(4*3)+(3*1)+(2*5)+(1*2)=88
88 % 10 = 8
So 51431-52-8 is a valid CAS Registry Number.

A novel catalytic activity of bismuth(III) salts in palladium(II)-catalyzed atom economical Michael-type hydroarylation of nitroalkenes with aryltin compounds

Ohe, Toshiyuki,Uemura, Sakae

, p. 1269 - 1271 (2002)

A novel catalytic effect of bismuth(III) salts such as BiCl3, Bi2O3, and Bi(NO3)3·5H2O has been disclosed in new palladium(II)-catalyzed Michael-type hydroarylation of nitroalkenes with aryltin compounds. The reaction is atom economical in the tin compounds and slightly fewer than four aryl groups of tetraaryltins can be transferred to the products.

Multifunctional isoquinoline-oxazoline ligands of chemical and biological importance

Li, Wei,Wang, Guotong,Lai, Jixing,Li, Shengkun

supporting information, p. 5902 - 5905 (2019/05/27)

Multifunctional isoquinoline-oxazolines (MIQOXs) were conceived and synthesized from commercially available chiral amino acids. The multifunctional role of MIQOXs was demonstrated by Pd-catalyzed highly enantioselective addition of arylboronic acids to nitrostyrenes, and by the discovery of novel antifungal candidates.

Stable and Reusable Palladium Nanoparticles-Catalyzed Conjugate Addition of Aryl Iodides to Enones: Route to Reductive Heck Products

Parveen, Naziya,Saha, Rajib,Sekar, Govindasamy

, p. 3741 - 3751 (2017/11/15)

An efficient, binaphthyl-backbone-stabilized palladium nanoparticles (Pd-BNP) catalyst for the 1,4-addition of aryl halides to enones has been developed. The scope of the reaction has been studied with various substituted and sterically hindered aryl hali
