Abstract

Official abstract text for this publication.

An object of this invention is to provide a simple method for producing sulfur tetrafluoride. The object is achieved by a method for producing sulfur tetrafluoride, comprising step A of reacting a fluorinated halogen compound with sulfur chloride, the fluorinated halogen compound being represented by formula: XFn, wherein X is chlorine, bromine, or iodine; and n is a natural number of 1 to 5.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for producing sulfur tetrafluoride, comprising reacting a fluorinated halogen compound with sulfur chloride, wherein the fluorinated halogen compound is IF 5 , BrF 3 , or a combination thereof. 2. The method according to claim 1 , wherein the fluorinated halogen compound is IF 5 . 3. The method according to claim 2 , wherein ICl is produced as a by-product, but no I 2 is produced. 4. The method according to claim 3 , wherein the sulfur chloride is sulfur monochloride. 5. The method according to claim 2 , wherein the sulfur chloride is sulfur monochloride. 6. The method according to claim 1 , wherein the sulfur chloride is sulfur monochloride. 7. A deoxyfluorination method of a carbonyl compound or a hydroxyl-containing organic compound, the method comprising employing a composition comprising sulfur tetrafluoride and ICl for the deoxyfluorination of the carbonyl compound or the hydroxyl-containing compound.
