Check Digit Verification of cas no

The CAS Registry Mumber 4971-61-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,7 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4971-61:
(6*4)+(5*9)+(4*7)+(3*1)+(2*6)+(1*1)=113
113 % 10 = 3
So 4971-61-3 is a valid CAS Registry Number.

CsOH catalyzed aerobic oxidative synthesis of p-quinols from multi-alkyl phenols under mild conditions

Liang, Yu-Feng,Wu, Kai,Liu, Zhiqing,Wang, Xiaoyang,Liang, Yujie,Liu, Chenjiang,Jiao, Ning

, p. 1334 - 1339 (2015/03/18)

p-Quinols are ubiquitous structural motifs of various natural products and pharmaceutical compounds, and versatile building blocks in synthetic chemistry. The reported methods for the synthesis of p-quinol require stoichiometric amounts of oxidants. Molecular oxygen is considered as an ideal oxidant due to its natural, inexpensive, and environmentally friendly characteristics. During the ongoing research of C-H bond hydroxylation, we found that multi-alkyl phenols could react with molecular oxygen under mild conditions. Herein, we describe an efficient oxidative de-aromatization of multi-alkyl phenols to p-quinols. 1 atm of molecular oxygen was used as the oxidant. Many multi-alkyl phenols could react smoothly at room temperature. Isotopic labeling experiment was also performed, and the result proved that the oxygen atom in the produced hydroxyl group is from molecular oxygen.

Organo-peroxyl compounds via catalytic oxidation of a hindered phenol and aniline utilizing new manganese(II) bis benzimidazole diamide based complexes

Bakshi, Ruchi,Mathur, Pavan

experimental part, p. 3477 - 3488 (2011/02/15)

Bis benzimidazole diamide ligand-N,N′-bis(2-methylbenzimidazolyl) propanediamide [GBMA = L] has been synthesized and utilized to prepare new Mn(II) complexes of general composition [Mn(L)X2]·nH 2O where X is an exogenous anionic ligand(X = Cl-, CH 3COO-, SCN-). The geometry of the ligand and its Mn(II) complex have been optimized at the level of UHF, by using ZINDO/1 method. Binding energies, heat of formation and bond lengths of geometry optimized structures for the ligand and complex have been obtained. The oxidation of 2,4,6-tri-tert.-butylphenol (TTBP) and 2,4,6-tri-tert.-butylaniline (TTBA) has been investigated using these Mn(II) complexes as catalyst and TBHP as an alternate source of oxygen. The organo-peroxyl compounds have been isolated and characterized by 1H NMR, 13C NMR, IR and mass data. A different product profile was obtained when H2O2 is used as an oxidant.

Electron transfer between protonated and unprotonated phenoxyl radicals

Omura, Kanji

, p. 858 - 867 (2008/09/19)

(Chemical Equation Presented) The reaction of phenoxyl radicals with acids is investigated. 2,4,6-Tri-tert-butylphenoxyl radical (13), a persistent radical, deteriorates in MeOH/PhH in the presence of an acid yielding 4-methoxycyclohexa-2,5-dienone 18a and the parent phenol (14). The reaction is facilitated by a strong acid. Treatment of 2,6-di-tert-butyl-4-methylphenoxyl radical (2), a short-lived radical, generated by dissociation of its dimer, with an acid in MeOH provides 4-methoxycyclohexa-2,5-dienone 4 and the products from disproportionation of 2 including the parent phenol (3). A strong acid in a high concentration favors the formation of 4 while the yield of 3 is always kept high. Oxidation of the parent phenol (33) with PbO2 to generate transient 2,6-di-tert-butylphenoxyl radical (35) in AcOH/H2O containing an added acid provides eventually p-benzoquinone 39 and 4,4′-diphenoquinone 42, the product from dimerization of 35. A strong acid in a high concentration favors the formation of 39. These results suggest that a phenoxyl radical is protonated by an acid and electron transfer takes place from another phenoxyl radical to the protonated phenoxyl radical, thus generating the phenoxyl cation, which can add an oxygen nucleophile, and the phenol (eq 5). The electron transfer is a fast reaction.
