31599-59-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31599-59-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,9 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31599-59:
(7*3)+(6*1)+(5*5)+(4*9)+(3*9)+(2*5)+(1*9)=134
134 % 10 = 4
So 31599-59-4 is a valid CAS Registry Number.

Conformational structure and energetics of 2- methylphenyl(2′methoxyphenyl)iodonium chloride: Evidence for solution clusters

Lee, Yong-Sok,Hodoscek, Milan,Chun, Joong-Hyun,Pike, Victor W.

, p. 10418 - 10423 (2010)

Diaryliodonium salts allow the efficient incorporation of cyclotronproduced [18F]fluoride ions into electron-rich and electron-deficient arenes to provide potential radiotracers for molecular imaging in vivo with positron emission tomography (P

Preparation and Synthetic Applicability of Imidazole-Containing Cyclic Iodonium Salts

Antonkin, Nikita S.,Vlasenko, Yulia A.,Yoshimura, Akira,Smirnov, Vladimir I.,Borodina, Tatyana N.,Zhdankin, Viktor V.,Yusubov, Mekhman S.,Shafir, Alexandr,Postnikov, Pavel S.

, p. 7163 - 7178 (2021/05/29)

A novel approach to the preparation of imidazole-substituted cyclic iodonium salts has been developed via the oxidative cyclization of 1-phenyl-5-iodoimidazole using a cheap and available Oxone/H2SO4 oxidative system. The structure of the new polycyclic heteroarenes has been confirmed by single-crystal X-ray diffractometry, revealing the characteristic structure features for cyclic iodonium salts. The newly produced imidazole-flanked cyclic iodonium compounds were found to readily engage in a heterocyclization reaction with elemental sulfur, affording benzo[5,1-b]imidazothiazoles in good yields.

N -Heterocyclic Carbene-Catalyzed Olefination of Aldehydes with Vinyliodonium Salts to Generate α,β-Unsaturated Ketones

Rajkiewicz, Adam A.,Kalek, Marcin

supporting information, p. 1906 - 1909 (2018/04/16)

An organocatalyzed metal-free, direct olefination of aldehydes with vinyliodonium salts has been achieved by an N-heterocyclic carbene-promoted C-H bond activation. The reaction proceeds under very mild conditions, delivering a range of (hetero)aryl-vinyl ketones in good yields. The retention of the double bond configuration is uniformly observed, and the application of 2-methoxyphenyl auxiliary group in iodonium salts secures a complete selectivity of the vinyl transfer.
