Catalytic sulfuration of dienes with metallocene polysulfides

Article abstract of DOI:10.1016/S0040-4039(98)02073-5

Elemental sulfur reacts with conjugated 1,3-dienes to give cyclic di- and tetrasulfides. The yield is significantly improved in the presence of catalytic amounts of organometallic polysulfides. The nature of this effect is discussed.
