The reaction of triphenylmethanesulfenyl chloride (3a) with acyclic disulfides 4 or 5 give the respective trisulfides 1 or 2 in moderate to good yield and selectivity. A mechanism is advanced to explain the chemistry.
Imides such as N-(morpholinothio)phthalimide are used to affect the vulcanization characteristics of sulfur vulcanizable polymers by increasing the state of vulcanization and/or improving scorch resistance and/or increasing the rate of vulcanization.

A coated article comprises a substrate and a self-healing coating disposed on a surface of the substrate, the self-healing coating comprising a metallic matrix; and a plurality of micro- or nano-sized particles dispersed in the metallic matrix; the micro- or nano-sized particles comprising an active agent disposed in a carrier comprising a micro- or nano-sized metallic container, a layered structure, a porous structure, or a combination comprising at least one of the foregoing.
Organoaminosilanes, such as without limitation di-iso-propylaminosilane (DIPAS), are precursors for the deposition of silicon containing films such as silicon-oxide and silicon-nitride films. Described herein are methods to make organoaminosilane compounds, or other compounds such as organoaminodisilanes and organoaminocarbosilanes, via the catalytic hydrosilylation of an imine by a silicon source comprising a hydridosilane.
Synthetically-derived S,S-heterodisubstituted disulfides that exhibit potent in vitro antibacterial activity against a variety of bacteria, including Staphylococcus aureus, methicillin-resistant Staphylococcus aureus and Francisella tularensis. The present invention provides compounds, methods and compositions effective to treat microbial/bacterial infections, and, especially, infections arising from bacteria which have developed resistance to conventional antibiotics.
