368-43-4 Usage

Chemical Properties

clear light yellow liquid

Uses

Benzenesulfonyl fluoride has been used in the preparation of α-sulfonyl phosphonates by direct sulfonylation of lithiated alkyl phosphonates.

General Description

The gas-phase fluorine migration reactions of radical cations of benzenesulfonyl fluoride have been studied by electron ionization tandem mass spectrometry.

Safety Profile

A poison by intraperitoneal route. Slightly irritating to sbn. Flammable when exposed to heat or flame. It can react vigorously with oxihzing materials. To fight fire, use water, foam, CO2, water spray or mist, dry chemical. When heated to decomposition it emits toxic fumes of Fand SO,. See also FLUORIDES and SULFATES.

Check Digit Verification of cas no

The CAS Registry Mumber 368-43-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,6 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 368-43:
(5*3)+(4*6)+(3*8)+(2*4)+(1*3)=74
74 % 10 = 4
So 368-43-4 is a valid CAS Registry Number.

Redox-Neutral Organometallic Elementary Steps at Bismuth: Catalytic Synthesis of Aryl Sulfonyl Fluorides

Cornella, Josep,Magre, Marc

, p. 21497 - 21502 (2022/01/03)

A Bi-catalyzed synthesis of sulfonyl fluorides from the corresponding (hetero)aryl boronic acids is presented. We demonstrate that the organobismuth(III) catalysts bearing a bis-aryl sulfone ligand backbone revolve through different canonical organometallic steps within the catalytic cycle without modifying the oxidation state. All steps have been validated, including the catalytic insertion of SO2 into Bi-C bonds, leading to a structurally unique O-bound bismuth sulfinate complex. The catalytic protocol affords excellent yields for a wide range of aryl and heteroaryl boronic acids, displaying a wide functional group tolerance.

Synthesis of Sulfones and Sulfonyl Derivatives using Sodium (tert-butyldimethylsilyl)oxymethanesulfinate

Paragraph 0908-0912; 0914; 0916-0917; 0919-0922; 0924-0927, (2021/04/29)

The present invention relates to a method for manufacturing a sulfone and sulfonyl derivative compound using sodium (tert-butyldimethylsilyl)oxymethanesulfinate, which is a novel organic sulfin salt, wherein the novel organic sulfin salt has good stability, environmental friendliness and economy, and is easy to handle, and thus significantly reduces the amount of transition metal catalysts and the amount of organic sulfin salts used when introducing aryl or alkenyl. Also, alkylation, arylation, amination, and fluorination are all possible during secondary functionalization. Therefore, the present invention can be usefully used in preparation and mass production of various kinds of sulfones and derivatives thereof including asymmetric sulfone derivatives.
