857591-32-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 857591-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,5,9 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 857591-32:
(8*8)+(7*5)+(6*7)+(5*5)+(4*9)+(3*1)+(2*3)+(1*2)=213
213 % 10 = 3
So 857591-32-3 is a valid CAS Registry Number.

Implication of a Silyl Cobalt Dihydride Complex as a Useful Catalyst for the Hydrosilylation of Imines

Barbazanges, Marion,Bories, Cassandre C.,Derat, Etienne,Petit, Marc

, p. 14262 - 14273 (2021/11/27)

Here, we describe the formation and use of silyl cobalt (III) dihydride complexes as powerful catalysts for the hydrosilylation of a variety of imines starting from a low-valent well-defined cobalt (I) complex. The reaction is efficient at low catalyst loadings with a diverse range of imines bearing various protecting groups, as well as aliphatic ketimines and quinoline. Kinetics, DFT calculations, NMR spectroscopic studies, deuteration experiments, and X-ray diffraction analyses allowed us to propose a catalytic cycle based on silyl dihydrocobalt (III) complexes performing a hydrocobaltation.

Hydrogen-Borrowing Amination of Secondary Alcohols Promoted by a (Cyclopentadienone)iron Complex

Aiolfi, Francesco,Bai, Xishan,Cettolin, Mattia,Dal Corso, Alberto,Gennari, Cesare,Piarulli, Umberto,Pignataro, Luca

, p. 3545 - 3555 (2019/09/09)

Thanks to a highly active catalyst, the scope of the (cyclopentadienone)iron complex-promoted 'hydrogen-borrowing' (HB) amination has been expanded to secondary alcohols, which had previously been reported to react only in the presence of large amounts of co-catalysts. A range of cyclic and acyclic secondary alcohols were reacted with aromatic and aliphatic amines giving fair to excellent yields of the substitution products. The catalyst was also able to promote the cyclization of diols bearing a secondary alcohol group with primary amines to generate saturated N-heterocycles.

NHC-carbene cyclopentadienyl iron based catalyst for a general and efficient hydrosilylation of imines

Castro, Luis C. Misal,Sortais, Jean-Baptiste,Darcel, Christophe

supporting information; experimental part, p. 151 - 153 (2012/01/06)

A general and efficient hydrosilylation of imines catalysed by a well defined NHC-carbene cyclopentadienyl iron complex has been developed. Both aldimines and ketimines are converted to the corresponding amines under mild conditions, and under visible light activation.
