4661-46-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4661-46-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4661-46:
(6*4)+(5*6)+(4*6)+(3*1)+(2*4)+(1*6)=95
95 % 10 = 5
So 4661-46-5 is a valid CAS Registry Number.

Nanoparticles of organosilane-based nitrite ionic liquid immobilized on silica for the diazotization of aniline derivatives and subsequent synthesis of azo dyes

Valizadeh, Hassan,Amiri, Mohammad,Hosseinzadeh, Fatemeh

experimental part, p. 1308 - 1313 (2012/03/27)

Imidazolium based nitrite ionic liquid containing trimethoxysilyl group was prepared from the reaction of N-methylimidazole and (3-chloropropyl) trimethoxysilane. This ionic liquid was immobilized on silica covalently to give nanoparticles with the imidazolium nitrite moiety remaining intact. The diazotization reaction was performed as a model reaction to examine the activity of these nanoparticles as a nitrosonium source. Excellent performance was exhibited in the diazotization reaction of various aniline derivatives in the presence of HCl under mild heterogeneous conditions (room temperature and short reaction time). In-situ coupling of diazonium salts to a range of tertiary anilines, phenols and naphthols afforded the requisite azo dyes in good yield, using standard experimental procedures.

Synthesis, structure, and glutathione peroxidase-like activity of amino acid containing ebselen analogues and diaryl diselenides

Selvakumar, Karuthapandi,Shah, Poonam,Singh, Harkesh B.,Butcher, Ray J.

experimental part, p. 12741 - 12755 (2011/12/04)

The synthesis of some ebselen analogues and diaryl diselenides, which have amino acid functions as an intramolecularly coordinating group (Se O) has been achieved by the DCC coupling procedure. The reaction of 2,2′- diselanediylbis(5-tert-butylisophthalic acid) or the activated ester tetrakis(2,5-dioxopyrrolidin-1-yl) 2,2′-diselanediylbis(5-tert- butylisophthalate) with different C-protected amino acids (Gly, L-Phe, L-Ala, and L-Trp) afforded the corresponding ebselen analogues. The used precursor diselenides have been found to undergo facile intramolecular cyclization during the amide bond formation reaction. In contrast, the DCC coupling of 2,2′-diselanediyldibenzoic acid with C-protected amino acids (Gly, L/D-Ala and L-Phe) affords the corresponding amide derivatives and not the ebselen analogues. Some of the representative compounds have been structurally characterized by single-crystal X-ray crystallography. The glutathione peroxidase (GPx)-like activities of the ebselen analogues and the diaryl diselenides have been evaluated by using the coupled reductase assay method. Intramolecularly stabilized ebselen analogues show slightly higher maximal velocity (Vmax) than ebselen. However, they do not show any GPx-like activity at low GSH concentrations at which ebselen and related diselenides are active. This could be attributed to the peroxide-mediated intramolecular cyclization of the corresponding selenenyl sulfide and diaryl diselenide intermediates generated during the catalytic cycle. Interestingly, the diaryl diselenides with alanine (l,l or d,d) amide moieties showed excellent catalytic efficiency (kcat/KM) with low KM values in comparison to the other compounds. Peroxidase-like activity: Reaction of compound 1 (see figure) with glutathione (GSH) leads to the formation of the corresponding selenenyl sulfide and diaryl diselenide intermediates. The reaction of these intermediates with H2O2 leads to the formation of 1 via arylselenenic acid. This process hampers the GPx-like activity at low GSH concentrations.

Synthesis and structural characterization of sulfur rich iron (II) carbonyl dimers: Facile reversible reaction with carbon monoxide

Carcer, Inigo Aguirre de,Heinekey, D. Michael

scheme or table, p. 840 - 844 (2009/05/27)

The sulfur-rich iron carbonyl dimer complexes [Fe(CO)2(S′SiS2)]2 (2), and [Fe(CO)(S′SiS2)]2 (3) have been prepared. The [2Fe-2S] cores of the new complexes are planar. The binding mode of the tridentate sulfur ligand in complex 2 is facial with a S(thiolate)-Fe-S(thiolate) angle of 92°, while in complex 3, the S′SiS2 ligand binds the metal with a S(thiolate)-M-S(thiolate) angle of 120°. The Fe-Fe distance is reduced from 3.45 A? in complex 2 to 2.78 A? in the 32 electron dimer complex 3. Complexes 2 and 3 are at equilibrium in solution and can be readily interconverted by addition or removal of CO.
