16825-75-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16825-75-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,2 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16825-75:
(7*1)+(6*6)+(5*8)+(4*2)+(3*5)+(2*7)+(1*5)=125
125 % 10 = 5
So 16825-75-5 is a valid CAS Registry Number.

Mild and efficient synthesis of iodylarenes using Oxone as oxidant

Soldatova, Natalia,Postnikov, Pavel,Troyan, Anna A.,Yoshimura, Akira,Yusubov, Mekhman S.,Zhdankin, Viktor V.

supporting information, p. 4254 - 4256 (2016/08/25)

Mild and efficient method for the preparation of iodylarenes by oxidation of iodoarenes with Oxone in aqueous acetonitrile at room temperature is described. This new procedure allows the preparation of various iodylarenes with electron-donating or electron-withdrawing substituents in the aromatic ring including the previously unknown 1,2-diiodylbenzene.

RuCl3-catalyzed oxidation of iodoarenes with peracetic acid: New facile preparation of iodylarenes

Koposov, Alexey Y.,Karimov, Rashad R.,Pronin, Andrey A.,Skrupskaya, Tatyana,Yusubov, Mekhman S.,Zhdankin, Viktor V.

, p. 9912 - 9914 (2007/10/03)

New facile methodology for the preparation of pentavalent iodine compounds using peracetic acid as an oxidant in the presence of catalytic amounts of ruthenium trichloride is described. The new procedure allows the preparation of several previously unknown iodylarenes bearing strongly electron-withdrawing CF3 groups in the aromatic ring.

Simple anf Efficient Palladium-Catalyzed Carbonylation of Iodoxyarenes in Water under Mild Conditions

Grushin, Vladimir V.,Alper, Hovard

, p. 4794 - 4795 (2007/10/02)

Iodoxyarenes (ArIO2) readily react with CO (1 atm) in water, in the presence of Na2 (0.1percent) and Na2CO3 at 40-50 deg C, to give the corresponding carboxylic acids, ArCOOH, in 55-89percent isolated yield.Particulary attractive features of the reaction are that, unlike most iodoarenes, ArIO2 can be carbonylated in aqueous media without any organic solvents, due to their solubility in water and high reactivity.
