23600-48-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23600-48-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,6,0 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 23600-48:
(7*2)+(6*3)+(5*6)+(4*0)+(3*0)+(2*4)+(1*8)=78
78 % 10 = 8
So 23600-48-8 is a valid CAS Registry Number.

Redox-Neutral Selenium-Catalysed Isomerisation of para-Hydroxamic Acids into para-Aminophenols

Chuang, Hsiang-Yu,Schupp, Manuel,Meyrelles, Ricardo,Maryasin, Boris,Maulide, Nuno

, p. 13778 - 13782 (2021/03/31)

A selenium-catalysed para-hydroxylation of N-aryl-hydroxamic acids is reported. Mechanistically, the reaction comprises an N?O bond cleavage and consecutive selenium-induced [2,3]-rearrangement to deliver para-hydroxyaniline derivatives. The mechanism is studied through both 18O-crossover experiments as well as quantum chemical calculations. This redox-neutral transformation provides an unconventional synthetic approach to para-aminophenols.

Novel 3/4-((Substitutedbenzamidophenoxy)methyl)-N-hydroxybenzamides/propenamides and its use

-

Paragraph 0101; 0103; 0104, (2020/03/17)

The present invention relates to novel 3/4-((substituted benzamidophenoxy) methyl) -N-hydroxy benzamide/propenamide, as a histone deacetylase (HDAC) inhibitor, and to an anticancer composition comprising the same as an active ingredient. More specifically

Introduction of a hydroxy group at the para position and N-iodophenylation of N-arylamides using phenyliodine(III) bis(trifluoroacetate)

Itoh, Naoki,Sakamoto, Takeshi,Miyazawa, Etsuko,Kikugawa, Yasuo

, p. 7424 - 7428 (2007/10/03)

The reaction of anilides with phenyliodine(III) bis(trifluoroacetate) (PIFA) in trifluoroacetic acid (TFA), TFA-CHCl3, or hexafluoroisopropyl alcohol (HFIP) is described. When the acyl group of the anilide is highly electronegative, such as trifluoroacetyl, or the phenyl group is substituted with an electron-withdrawing group, the 4-iodophenyl group is transferred from PIFA to the amide nitrogen to afford acetyldiarylamines. On the other hand, when the acyl group contains an electron-donating function, such as 4-methoxyphenyl, or the phenyl group is substituted with an electron-donating group, a trifluoroacetoxy group is transferred to the para position of the anilide aromatic ring. This group is hydrolyzed during workup to produce the corresponding phenol.
