Check Digit Verification of cas no

The CAS Registry Mumber 710331-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,0,3,3 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 710331-52:
(8*7)+(7*1)+(6*0)+(5*3)+(4*3)+(3*1)+(2*5)+(1*2)=105
105 % 10 = 5
So 710331-52-5 is a valid CAS Registry Number.

Well-Defined β-Diketiminatocobalt(II) Complexes for Alkene Cyclohydroamination of Primary Amines

Lepori, Clément,Gómez-Orellana, Pablo,Ouharzoune, Allissa,Guillot, Régis,Lledós, Agusti,Ujaque, Gregori,Hannedouche, Jér?me

, p. 4446 - 4451 (2018/05/22)

A well-defined low-coordinate β-diketiminatocobalt(II) alkyl complex is reported as an active precatalyst for the selective alkene cyclohydroamination of unprotected primary amines under mild conditions (rt-90 °C). The reaction mechanism has been investigated by deuterium-labeling, kinetics, and stoichiometric experiments and in-depth computational DFT studies. On the basis of these studies, we propose a stepwise noninsertive mechanism that features a rate-determining nucleophilic attack of the amido group of a monomeric cobalt(II) amidoalkene-aminoalkene adduct intermediate to the noncoordinated pendant alkene followed by a rapid proton transfer from the coordinated aminoalkene to the cyclized adduct.

Intramolecular hydroamination of aminoalkenes using rhodium(I) and Iridium(I) complexes with N,N-and P,N-donor ligands

Nguyen, Thi O.,Man, Bradley Y.-W.,Hodgson, Richard,Messerle, Barbara A.

scheme or table, p. 741 - 746 (2012/07/17)

Cationic rhodium(i) and iridium(i) complexes containing the bidentate heterocyclic N,N-donor ligand bis(1-pyrazolyl)methane (bpm) and the counterion tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (BArF-) were found to be efficient catalysts for the cycliz

Synthesis, characterization, and reactivity of aluminum alkyl/amide complexes supported by guanidinate and monoanionic OCO-pincer ligands

Koller, Juergen,Bergman, Robert G.

scheme or table, p. 3350 - 3356 (2010/10/04)

The synthesis and characterization of mixed alkyl/amide Al complexes supported by guanidinate and monoanionic OCO-pincer ligands are described. In situ generation of the lithium-guanidinate reagents via reaction of carbodiimides and lithium-amide reagents, followed by reaction with the corresponding AlMexCl3-x reagents, resulted in the formation of compounds 1-3. Subsequent reaction with lithium arylamide reagents provided access to mixed alkyl/amide-and bis-amide-substituted complexes 4-6, which were characterized by multinuclear NMR spectroscopy and elemental analysis. Single-crystal X-ray diffraction of compounds 5a and 6a confirmed the monomeric nature of these complexes and revealed the influence of the alkyl/amide functionalities on the bonding of the guanidinate ligands. A similar synthetic approach resulted in isolation of an OCO-pincer-supported Al dialkyl complex, which was also fully characterized. In contrast to the guanidinate compounds, complex 8 showed activity toward intramolecular hydroamination of 2,2-diphenylpent-4-en-1-amine.

Air-and water-stable catalysts for hydroamination/cyclization. Synthesis and application of CCC-NHC pincer complexes of RH and Ir

Bauer, Eike B.,Andavan, G. T. Senthil,Hollis, T. Keith,Rubio, Ramel J.,Cho, Joon,Kuchenbeiser, Glenn R.,Helgert, Theodore R.,Letko, Christopher S.,Tham, Fook S.

scheme or table, p. 1175 - 1178 (2009/04/11)

The scope of CCC-NHC pincer complex synthetic methodology by metalation/transmetalation has been extended to Ir. Structural characterization revealed that it is isomorphous with the Rh complex. Both Rh and Ir complexes are efficient catalysts for the hydr
