Abstract

RhH (PPh3) 4 and cis-1, 2-bis (diphenylphosphino) ethylene (dppv) catalyze the exchange of sulfur atoms between sulfur and organic polysulfides. The exchange of dialkyl trisulfides with sulfur proceeds at a high efficiency within 5min at room temperature yielding a mixture of organic polysulfides.
