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.

In an effort to expand the availability of simple polysulfides for H2S donation, we report here the synthesis and H2S release profiles of bis(aryl) and bis(alkyl) tetrasulfides. The tetrasulfide donors release H2S in a first-order dependence on reduced glutathione (GSH) and release more H2S than the commonly used trisulfide DATS.

The reaction of aromatic thiols with sulfur dichloride and sulfur monochloride to form the corresponding aromatic trisulfides, 2a-d, and tetrasulfides, 3a-d, has been optimized with respect to yield and purity. The use of pyridine as an amine base and the
