 and)
Hydrogen thioperoxide, also called oxadisulfane or sulfur hydride hydroxide, is the chemical with the structure H–S–O–H. It can be considered as the simple sulfur-substituted analog of the common hydrogen peroxide (H–O–O–H) chemical, and as the simplest hydrogen chalcogenide containing more than one … See more Hydrogen thioperoxide has been synthesized in labs by photolysis of a mixture of ozone and hydrogen sulfide frozen in argon at 8 K and by pyrolysis of di-tert-butyl sulfoxide. Yet another synthesis is by an electric … See more Hydrogen thioperoxide molecules have a gauche conformation. They are unsymmetrical, but have a low barrier to convert from left-hand to right-hand forms, so that the molecule … See more Two molecules of hydrogen thioperoxide can undergo cyclocondensation to form sulfinothioic acid HS(=O)SH and water.
