87562-51-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87562-51-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,6 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87562-51:
(7*8)+(6*7)+(5*5)+(4*6)+(3*2)+(2*5)+(1*1)=164
164 % 10 = 4
So 87562-51-4 is a valid CAS Registry Number.

Controlled Reduction of Nitriles by Sodium Hydride and Zinc Chloride

Chiba, Shunsuke,Ong, Derek Yiren

supporting information, p. 1369 - 1378 (2020/04/27)

A new protocol for the controlled reduction of nitriles to aldehydes was developed using a combination of sodium hydride and zinc chloride. The iminyl zinc intermediates derived from aromatic nitriles could be further functionalized with allylmetal nucleophiles to afford homoallylamines. As the method allows the reduction of various aliphatic and aromatic nitriles with a concise procedure under milder reaction conditions and exhibits wide functional group compatibility, it is well suited for use in various opportunities in chemical synthesis.

An Iodine-Catalyzed Hofmann-L?ffler Reaction

Martínez, Claudio,Mu?iz, Kilian

supporting information, p. 8287 - 8291 (2015/07/07)

Iodine reagents have been identified as economically and ecologically benign alternatives to transition metals, although their application as molecular catalysts in challenging C-H oxidation reactions has remained elusive. An attractive iodine oxidation catalysis is now shown to promote the convenient conversion of carbon-hydrogen bonds into carbon-nitrogen bonds with unprecedented complete selectivity. The reaction proceeds by two interlocked catalytic cycles comprising a radical chain reaction, which is initiated by visible light as energy source. This unorthodox synthetic strategy for the direct oxidative amination of alkyl groups has no biosynthetic precedence and provides an efficient and straightforward access to a general class of saturated nitrogenated heterocycles.
