871890-63-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 871890-63-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,8,9 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 871890-63:
(8*8)+(7*7)+(6*1)+(5*8)+(4*9)+(3*0)+(2*6)+(1*3)=210
210 % 10 = 0
So 871890-63-0 is a valid CAS Registry Number.

Aryl-Diadamantyl Phosphine Ligands in Palladium-Catalyzed Cross-Coupling Reactions: Synthesis, Structural Analysis, and Application

Sinai, ádám,Simkó, Dániel Cs.,Szabó, Fruzsina,Paczal, Attila,Gáti, Tamás,Bényei, Attila,Novák, Zoltán,Kotschy, András

supporting information, p. 1122 - 1128 (2020/03/03)

Synthesis, temperature-dependent NMR structure investigation and utilization of a new, stable and easily accessible aryl-diadamantylphosphine ligand family is reported. The bulky and electron-rich phosphorus center of the ligand enhances the catalytic activity of palladium in cross-coupling reactions of sterically demanding ortho-substituted aryl halides. In our study, we demonstrated the synthetic applicability of the new phosphine ligands in Buchwald-Hartwig and tosyl hydrazone coupling reactions.

Ni(0)/NHC-catalyzed amination of N-heteroaryl methyl ethers through the cleavage of carbonoxygen bonds

Tobisu, Mamoru,Yasutome, Ayaka,Yamakawa, Ken,Shimasaki, Toshiaki,Chatani, Naoto

supporting information; experimental part, p. 5157 - 5161 (2012/07/31)

Ni(0)/NHC-based catalyst system can promote the amination of N-heteroaryl methyl ethers via the cleavage of normally unreactive carbon-oxygen bonds. Electron-deficient N-heteroarenes including pyridine, quinoline, isoquinoline, and quinoxaline undergo amination to afford aminopyridine and related heteroarenes, which constitute an important class of compounds.
