Abstract: The present invention relates to a method for the manufacture of cyclododecasulfur, a cyclic sulfur allotrope wherein the number of sulfur (S) atoms in the allotrope's homocyclic ring is 12. The method includes reacting a metallasulfur derivative with an oxidizing agent in a reaction zone to form a cyclododecasulfur-containing reaction mixture.
