97728-46-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97728-46-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,7,2 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97728-46:
(7*9)+(6*7)+(5*7)+(4*2)+(3*8)+(2*4)+(1*6)=186
186 % 10 = 6
So 97728-46-6 is a valid CAS Registry Number.

Intermolecular C-O Bond Formation with Alkoxyl Radicals: Photoredox-Catalyzed α-Alkoxylation of Carbonyl Compounds

Banoun, Camille,Bourdreux, Flavien,Magnier, Emmanuel,Dagousset, Guillaume

supporting information, p. 8926 - 8930 (2021/11/17)

Due to the high reactivity of alkoxyl (RO·) radicals and their propensity to easily undergo β-scission or Hydrogen Atom Transfer (HAT) reactions, intermolecular alkoxylations involving RO· radicals are barely described. We report herein for the first time the efficient intermolecular trapping of alkoxyl radicals by silyl enol ethers. This photoredox-mediated protocol enables the introduction of both structurally simple and more complex alkoxy groups into a wide range of ketones and amides.

Oxidative iodination of carbonyl compounds using ammonium iodide and oxone

Marri, Mahender Reddy,MacHarla, Arun Kumar,Peraka, Swamy,Nama, Narender

supporting information; experimental part, p. 6554 - 6559 (2012/01/02)

A simple, efficient, mild, and regioselective method for oxyiodination of carbonyl compounds has been reported by using NH4I as the source of iodine and Oxone as an oxidant. Various carbonyl compounds such as aralkyl ketones, aliphatic ketones (acyclic and cyclic), and β-keto esters proceeded to the respective α-monoiodinated products in moderate to excellent yields. Unsymmetrical aliphatic ketones reacted smoothly yielding a mixture of 1-iodo and 3-iodo ketones with the predominant formation of 1-iodoproduct.
