501-58-6 Usage

Purification Methods

Chromatograph it on basic alumina and elute with *benzene. Then crystallise the residue from 2:2:1 (v/v) methanol/ethanol/*benzene or Me2CO. [Beilstein 16 H 112, 16 I 237, 16 II 43, 16 III 93, 16 IV 172.]

Check Digit Verification of cas no

The CAS Registry Mumber 501-58-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 501-58:
(5*5)+(4*0)+(3*1)+(2*5)+(1*8)=46
46 % 10 = 6
So 501-58-6 is a valid CAS Registry Number.

Well-defined vanadium organoazide complexes and their conversion to terminal vanadium imides: Structural snapshots and evidence for a nitrene capture mechanism

Harman, W. Hill,Lichterman, Michael F.,Piro, Nicholas A.,Chang, Christopher J.

, p. 10037 - 10042 (2012)

We report the synthesis and structural characterization of a family of well-defined organoazide complexes supported by a three-fold-symmetric pyrrolide scaffold and their conversion to the corresponding terminal imido congeners. Kinetic measurements on a

Bifunctional Cs?Au/Co3O4 (Basic and Redox)-Catalyzed Oxidative Synthesis of Aromatic Azo Compounds from Anilines

Akinnawo, Christianah Aarinola,Alimi, Oyekunle Azeez,Fapojuwo, Dele Peter,Meijboom, Reinout,Mogudi, Batsile M.,Onisuru, Oluwatayo Racheal,Oseghale, Charles O.

supporting information, p. 5063 - 5073 (2021/09/30)

An eco-friendly alkali-promoted (Cs?Au/Co3O4) catalyst, with redox and basic properties for the oxidative dehydrogenative coupling of anilines to symmetrical and unsymmetrical aromatic azo compounds, was developed. We realized a base additive- and molecular O2 oxidant-free process (using air), with reasonable reusability of the catalyst achieved under milder reaction conditions. Notably, the enhanced catalytic activity was also linked to the increased basic site concentration, low reduction temperatures, and the effect of lattice oxygen on the nanomaterials. The increased basic strength of the cation-promoted catalyst improved the electron density of the active Au species, resulting in higher yields of the desired aromatic azo compounds.

Electrosynthesis of Azobenzenes Directly from Nitrobenzenes

Ma, Yanfeng,Wu, Shanghui,Jiang, Shuxin,Xiao, Fuhong,Deng, Guo-Jun

, p. 3334 - 3338 (2021/10/29)

The electrochemical reduction strategy of nitrobenzenes is developed. The chemistry occurs under ambient conditions. The protocol uses inert electrodes and the solvent, DMSO, plays a dual role as a reducing agent. Its synthetic value has been demonstrated by the highly efficient synthesis of symmetric, unsymmetric and cyclic azo compounds.
