917-57-7 Usage

Uses

Vinyl lithium is a reactive intermediate for the formation of vinyl alcohols from aldehydes, vinyl ketones from organic acids, vinyl sulfides from disulfides, and monosubstituted alkenes from organic halides.

Check Digit Verification of cas no

The CAS Registry Mumber 917-57-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,1 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 917-57:
(5*9)+(4*1)+(3*7)+(2*5)+(1*7)=87
87 % 10 = 7
So 917-57-7 is a valid CAS Registry Number.

Synthesis and Reactivity of Reduced α-Diimine Nickel Complexes Relevant to Acrylic Acid Synthesis

Joannou, Matthew V.,Bezdek, Máté J.,Albahily, Khalid,Korobkov, Ilia,Chirik, Paul J.

The aryl-substituted α-diimine (DI) nickel vinyl complex (iPrDI)Ni(CH=CH2) (iPrDI = [2,6-(iPr)2C6H3N=C(CH3)]2) was synthesized and structurally characterized. The complex is dimeric in the solid state and has a distorted-square-planar geometry at nickel. A combination of single-crystal X-ray diffraction, EPR, magnetic susceptibility, and NMR analyses was used to elucidate the electronic structure of the compound, and it is best described as a low-spin Ni(II) derivative with a singly reduced α-diimine chelate. Addition of CO2 to the nickel vinyl complex resulted in insertion into the nickel-carbon bond to yield the corresponding nickel acrylate (iPrDI)Ni(κ2-O2CCH=CH2). EPR spectroscopy coupled with DFT calculations established that the S = 1/2 product maintains the nickel(II) oxidation state with an α-diimine-centered radical. Addition of acrylic acid to (iPrDI)Ni(CH=CH2) induced rapid, net bimetallic reductive elimination to release butadiene and produced the metastable olefin-bound acrylic acid complex (iPrDI)Ni(κ2-CH2=CHCO2H). Over the course of 2 h at 23 °C, this complex underwent a net oxidation to produce (iPrDI)Ni(κ2-O2CCH=CH2), with concomitant loss of H2.

Enantioselective Conjunctive Cross-Coupling of Bis(alkenyl)borates: A General Synthesis of Chiral Allylboron Reagents

Edelstein, Emma K.,Namirembe, Sheila,Morken, James P.

supporting information, p. 5027 - 5030 (2017/05/04)

Palladium-catalyzed conjunctive cross-coupling is used for the synthesis of enantioenriched allylboron reagents. This reaction employs nonsymmetric bis(alkenyl)borates as substrates and appears to occur by a mechanism that involves selective activation of the less substituted alkene followed by migration of the more substituted alkene during the course of a Pd-induced metalate rearrangement.
