A straightforward strategy involving photocatalysis has been established for accessing trisulfide dioxides from readily achieved symmetrical tetrasulfides. Stern-Volmer analysis and radical quenching experiments demonstrated the occurrence of a single electron transfer between the photocatalyst and sulfinic acid. Bioactive molecules such as the antihypertensive drug captopril, allicin derivatives, amino acids and terpenes were efficiently and reversibly linked through sulfur-sulfur covalent bonds. Furthermore, flow-setup syntheses of trisulfide dioxides were successfully achieved on the gram scale, indicating the great potential of the developed protocol for practical industrial applications.

experimental part, p. 3623 - 3631 (2012/07/16)
The central focus of this study is on the antibacterial and antifungal properties of synthetically produced S,S′-bis(heterosubstituted) disulfides as a means to control the growth of various infection-causing pathogens. Staphylococcus aureus, Francisella tularensis and Candida albicans were each found to be highly susceptible to several of these compounds by agar or broth dilution and Kirby-Bauer diffusion assays. These structurally simple, low molecular weight disulfides have shown promising bioactivities and may serve as leads to the development of effective new antibacterials for pathogenic bacteria such as methicillin-resistant S. aureus and F. tularensis.

Page/Page column 13; 16, (2009/05/30)
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.
Use of a sacriflcial-sulfur electrode in electroorganic chemistry. V. Formation of the sequence CSSSC from S and thiols or thiolates

At a working potential of about +2.0 V (vs SCE) the carbon-sulfur electrode is a source of the electrogenerated cation S2+. In organic media, this electrophile reacts with thiols (or thiolates) to give a mixture of polysulfides of which the trisulfide is the main product. The reaction between electrogenerated Sy2- and alkyl halides is less selective. Elsevier,.
REACTION OF SULFUR DIOXIDE WITH THIOLS CATALYZED BY BORON TRIFLUORIDE ETHERATE. EVIDENCE FOR A POSSIBLE INTERVENTION OF DITHIOSULFITE AS A REACTION INTERMEDIATE.

The reaction of sulfur dioxide (SO//2) with 1-propanethiol (NPT), 2-propanethiol (IPT), or 2-methyl-2-propanethiol (TBT) catalyzed by boron trifluoride ethrate (BF//3OEt//2) was investigated. The ratios of dialkyl trisulfide to dialkyl disulfide obtained (RSSSR/RSSR) at an early stage of the reaction were larger than 1 for the reaction of TBT and less than 1 for the reaction of NPT or IPT. The reaction of dithiosulfites with BF//3OEt//2 in the presence or absence of thiol was investigated. From a consideration of the similarity of the composition of the sulfides formed in the reaction of dithiosulfites with BF//3OEt//2 to those in the reaction of SO//2 witn thiol in the presence of BF//3OEt//2, the possibility of the intervention of dithiosulfite as a reaction intermediate in the reaction of SO//2 with thiol is discussed.
