7605-30-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7605-30-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,0 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7605-30:
93 % 10 = 3
So 7605-30-3 is a valid CAS Registry Number.

Method for preparing beta-carbonyl sulfone


Paragraph 0018; 0019, (2020/03/12)

The invention discloses a method for preparing beta-carbonyl sulfone. The preparation method comprises the following steps: by taking an alpha-carbonyl diazo compound and sodium arylsulfinate as reaction substrates, cheap silver nitrate as an optimal catalyst, 1, 10-phenanthroline as a ligand and potassium persulfate as an oxidant, carrying out coupling reaction in a mixed solvent of acetonitrileand water to obtain the beta-carbonyl sulfone compound. Compared with the prior art, the method has the advantages of wide reaction substrate range, short reaction time, high reaction yield, mild reaction conditions and the like. Non-toxic and harmless reagents are used as reaction raw materials, so that the method is harmless to the environment and meets the requirements of modern green chemicaldevelopment. Post-reaction treatment is simple, and separation and purification are facilitated. In addition, the reaction can realize gram-scale synthesis, and lays a foundation for practical application.

Switching of Sulfonylation Selectivity by Nature of Solvent and Temperature: The Reaction of β-Dicarbonyl Compounds with Sodium Sulfinates under the Action of Iron-Based Oxidants

, p. 4179 - 4188 (2019/05/08)

Selectivity of sulfonylation of β-keto esters with sodium sulfinates under the action of iron(III) salts as oxidants can be regulated by the type of solvent used and the reaction temperature. α-Sulfonyl β-keto esters are obtained when the process is conducted in THF/H2O solution at 40 °C. The change of the solvent to iPrOH/H2O and refluxing of a reaction mixture provides α-sulfonyl esters – the products of successive sulfonylation-deacylation. When β-diketones are applied as starting materials, only α-sulfonyl ketones are formed. The reaction pathway includes sulfonylation of dicabonyl compounds under the action of Fe(III) to form α-sulfonylated dicarbonyl compounds, which are then attacked by a solvent as the nucleophile, resulting in the products of successive sulfonylation-deacylation. Participation of the solvent in the reaction pathway determines the products structure.

Catalyst-free oxidation of sulfides to sulfoxides and diethylamine catalyzed oxidation of sulfides to sulfones using Oxone as an oxidant


, p. 6875 - 6888 (2017/10/06)

Abstract: We describe here our journey from the failure of our attempts in controlled oxidation of sulfides to sulfoxides using an Oxone–KBr combination to our success in the development of a catalyst-free protocol for the oxidation of sulfides to sulfoxides using Oxone as an oxidant. We also describe the failure of our attempts at the oxidation of sulfides to sulfones using an excess of Oxone–KBr as well as Oxone, and our success towards the development of a rapid, scalable and chromatography-free protocol for the oxidation of sulfides to sulfones using diethylamine–Oxone as an unprecedented catalyst–oxidant combination.
