Abstract

Official abstract text for this publication.

Preparation of sulfur fine chemicals from sulfur sources is described.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of manufacturing a silyl sulfide comprising contacting a sulfate-source with a silane reducing agent to produce the silyl sulfide. 2. The method of claim 1 , wherein the sulfate-source is a bisulfate. 3. The method of claim 2 , wherein the bisulfate is a bisulfate salt or is a bisulfate produced in situ from a sulfate salt and an acid or sulfuric acid and a base. 4. The method of claim 1 , wherein the silyl sulfide is a salt including the silyl sulfide is an anion and a cation. 5. The method of claim 1 , wherein the silane reducing agent is H n SiX 4-n where X is a halogen, a pseudohalogen, alkoxy, aryloxy, amido or arylamido and n is 1, 2, 3 or 4. 6. The method of claim 4 , wherein the silyl sulfide is [X 3 SiS] − wherein X is a halogen, a pseudohalogen, alkoxy, aryloxy, amido or arylamido. 7. The method of claim 4 , wherein the cation includes a nitrogen-based cation, a phosphorus-based cation, an alkali metal cation, an alkali-earth metal cation, or an ionic liquid cation.
