52120-10-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52120-10-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,1,2 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 52120-10:
(7*5)+(6*2)+(5*1)+(4*2)+(3*0)+(2*1)+(1*0)=62
62 % 10 = 2
So 52120-10-2 is a valid CAS Registry Number.

Radical and Nitrenoid Reactivity of 3-Halo-3-phenyldiazirines

Navrátil, Rafael,Tarábek, Ján,Linhart, Igor,Martin?, Tomá?

supporting information, p. 3734 - 3737 (2016/08/16)

3-Halo-3-phenyl-3H-diazirines (halogen = Br or Cl) undergo a dissociative single-electron transfer from alkyllithiums (RLi) in THF-based solvent mixtures. The resulting 3-phenyldiazirinyl radical, observed by EPR spectroscopy, is eventually transformed to benzonitrile. In Et2O, 2 equiv of RLi add to both nitrogens of halodiazirine N=N bond, affording N,N′-dialkylbenzamidines. The nitrenoid reactivity of some N-alkyl-1H-diazirine intermediates is manifested by their insertion into the α-C-H bond of THF or Et2O.

Samarium diiodide promoted synthesis of N,N′-disubstituted amidines

Xu, Fan,Sun, Jianhua,Shen, Qi

, p. 1867 - 1869 (2007/10/03)

An efficient one-step preparation of an N,N′-disubstituted amidine by the direct nucleophilic addition of an amine to the parent nitrile using catalytic amounts of SmI2 under relatively mild conditions is developed. Alkyl, benzyl and aryl amidi
