RhH(PPh3)4 and cis-1,2-bis(diphenylphosphino)ethylene (dppv) catalyze the exchange of sulfur atoms betweensulfur and organic polysulfides. The exchange of dialkyl trisulfides with sulfur proceeds at a high efficiency within 5 min at room temperature yielding a mixture of organic polysulfides.
capping as well as reducing agent to synthesize gold nanoparticles (TS-GNPs). In the process, it was discovered that among the selected DATs, only 1,3-di(but-1-ene)trisulfane could serve the purpose because of structural reasons. The reason for this intriguing selectivity has been investigated in detail using the experimental findings and theoretical calculations of the frontier molecular orbitals
