Abstract
Provided are methods for producing pentahalosulfur peroxides and monoxides, such as bis-(pentafluorosulfur) peroxide, that involve exposing a composition comprising a pentahalosulfur hypohalite, and optionally a sulfur hexahalide or trihalomethyl hypohalite, to a halogen free radical scavenger.

A method for producing a bis-(pentafluorosulfur) peroxide or monoxide comprising reacting, in the presence of at least one halogen radical scavenger, a first compound having the formula SF5OX with a second compound having the formula selected from SF5OX′ and SF5Y, wherein X and X′ are independently selected from —F and —Cl and Y is selected from —Cl or —Br, to form a reaction product having the formula SF5(O)nSF5, wherein n is 1 or 2.
A method for producing a nonsymmetrical pentafluorosulfur peroxide comprising reacting a first compound having the formula XOSF5 with a second compound having the formula X′OR in the presence of a halogen radical scavenger to form a product having the formula F5SOOR,
- wherein X and X′ are independently —F or —Cl;
- and
- R is CY′3 wherein Y′ is a halogen.
A method of forming an at least one pentahalogenated sulfur oxide compound comprising:
- (a) providing at least one halogen radical scavenger;
- and
- (b) reacting, in the presence of said halogen radical scavenger,
- a first compound of Formula (I):
- XOSY5 (I),
- with a second compound chosen from
- a compound of Formula (I),
- a compound of Formula (II):
- SY′6 (II), and
- a compound of Formula (III):
- ROX′ (III),
- wherein
- X is independently selected from —F and —Cl,
- X′ is independently selected from —F and —Cl,
- Y is independently selected from —F and —Cl,
- Y′ is independently selected from the group consisting of —F, —Cl, —Br, and —I, provided that not all Y's are the same type of halogen and
- R is independently a trihalomethyl group
- under conditions effective to produce the at least one pentahalogenated sulfur oxide compound.
