Disulfides and polysulfides have the structure R1SSnR2, in which chains of sulfur atoms are terminated by two groups that may be the same, different, or connected in a ring. Chapter 7 considers only substances where the S-R bond involves a carbon linkage; a review is available of structures such as ROSnOR and R2NSnNR2) Disulfides (n = 1) and their ...

Electrochemistry of Sulfur and Polysulfides in Ionic Liquids
The Journal of Physical Chemistry B, 2011The electrochemistry of elemental sulfur (S(8)) and the polysulfides Na(2)S(4) and Na(2)S(6) has been studied for the first time in nonchloroaluminate ionic liquids. The cyclic voltammetry of S(8) in the ionic liquids is different to the behavior reported in some organic solvents, with two reductions and one oxidation peak observed.

The paper deals briefly with the chemistry and formulation of polysulfide liquid polymers. It is primarily concerned with areas of application and performance of compounds based on the various liquid polymers. Criteria for the use of polysulfide sealants in the aircraft, automotive, building, and marine industries are given along with some case ...

Hydrogen Sulfide and Polysulfide Signaling
Antioxidants & Redox Signaling, 2017Hydrogen sulfide (H2S) has been demonstrated to have physiological roles such as neuromodulation, vascular tone regulation, cytoprotection, oxygen sensing, inflammatory regulation, and cell growth. Recently, hydrogen polysulfides (H2Sn) have been found to be produced by 3-mercaptopyruvate sulfurtransferase and to regulate the activity of ion channels ...

Organic Sulfides and Polysulfides. VI. Reactions of Metallic Oxides with Polysulfide Rubbers
Rubber Chemistry and Technology, 1958Abstract 1. Both mercaptides and disulfides were obtained by the reactions between benzyl mercaptan or tolyl mercaptan with zinc oxide or lead oxide. Qualitatively, mercaptides were formed from benzyl mercaptan easier than from tolyl mercaptan, and lead oxide reacted with mercaptan easier than zinc oxide with mercaptan.
