558-25-8 Usage

Chemical Properties

clear colorless to yellow liquid

General Description

Liquid.

Air & Water Reactions

On contact with moisture METHANESULFONYL FLUORIDE produces highly corrosive and toxic fumes of hydrogen fluoride gas.

Reactivity Profile

METHANESULFONYL FLUORIDE is corrosive, toxic liquid. Vigorous reaction with water, steam, alkali. A dangerous storage hazard. On contact with moisture METHANESULFONYL FLUORIDE produces highly corrosive and toxic fumes of hydrogen fluoride gas. When heated to decomposition METHANESULFONYL FLUORIDE emits toxic fumes of fluoride, and oxides of sulfur [M. K.]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

Health Hazard

Highly toxic when inhaled.

Fire Hazard

When heated to decomposition, METHANESULFONYL FLUORIDE emits very toxic fumes of fluorides and sulfur oxides.

Check Digit Verification of cas no

The CAS Registry Mumber 558-25-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 558-25:
(5*5)+(4*5)+(3*8)+(2*2)+(1*5)=78
78 % 10 = 8
So 558-25-8 is a valid CAS Registry Number.

Trifluoromethyl Nonaflate: A Practical Trifluoromethoxylating Reagent and its Application to the Regio- and Stereoselective Synthesis of Trifluoromethoxylated Alkenes

Hammond, Gerald B.,Kumon, Tatsuya,Lu, Zhichao,Umemoto, Teruo

supporting information, p. 16171 - 16177 (2021/06/27)

The trifluoromethoxy group has elicited much interest among drug and agrochemical discovery teams because of its unique properties. We developed trifluoromethyl nonafluorobutanesulfonate (nonaflate), TFNf, an easy-to-handle, bench-stable, reactive, and scalable trifluoromethoxylating reagent. TFNf is easily and safely prepared in a simple process in large scale and the nonaflyl part of TFNf can easily be recovered as nonaflyl fluoride after usage and recycled. The synthetic potency of TFNf was showcased with the underexplored synthesis of various trifluoromethoxylated alkenes, through a high regio- and stereoselective hydro(halo)trifluoromethoxylation of alkyne derivatives such as haloalkynes, alkynyl esters, and alkynyl sulfones. The synthetic merits of TFNf were further underscored with a high-yielding and smooth nucleophilic trifluoromethoxylation of alkyl triflates/bromides and primary/secondary alcohols.

One-pot fluorosulfurylation of Grignard reagents using sulfuryl fluoride

Lee, Cayo,Ball, Nicholas D.,Sammis, Glenn M.

supporting information, p. 14753 - 14756 (2019/12/23)

Herein, we report a new method for the one-pot syntheses of sulfonyl fluorides. Addition of an alkyl, aryl, or heteroaryl Grignard to a solution of sulfuryl fluoride at ambient temperature affords the desired sulfonyl fluorides in 18-78% yield. Furthermore, this method is applicable for in situ sequential reactions, whereby the Grignard reagent can be converted to the corresponding diarylsulfone, sulfonate ester, or sulfonamide in a one-pot process.

METHOD FOR PRODUCING FLUORINATED ALKANE, METHOD FOR SEPARATING AND RECOVERING AMIDINE BASE, AND METHOD FOR USING RECOVERED AMIDINE BASE

-

Paragraph 0177, (2018/05/17)

The present invention provides: a method for producing a fluorinated alkane represented by the formula (2): R2—F, wherein an alcohol having 3 to 5 carbon atoms is fluorinated by a fluorinating agent represented by the formula (1): R1SO2F in the absence of a solvent, and in the presence of a base selected from the group consisting of an amidine base and a phosphazene base; a method for separating and recovering an amidine base from an amidine base-sulfonate complex represented by the following formula (5); and a method for using a recovered amidine base. In the formula, R1 represents a methyl group, an ethyl group or an aromatic group, R2 represents an alkyl group having 3 to 5 carbon atoms, and n is 0 or 2.
