Abstract:A new procedure was developed for preparing 1,2,3-propanetrithiol from available initial compounds. 1,2,3-Trichloroethane reacts with sodium disulfide prepared by dissolving sulfur in the system NaOH-N_2H_4 · H_2O-H_2O to give a disulfide dendrimeric polymer, thiokol, in almost quantitative yield. This polymer is subjected to reductive cleavage with an alkaline solution of hydrazine hydrate, which is followed by acidification with HCl. The yield of 1,2,3-propanetrithiol exceeds 60%. The synthesis can be performed as a one-pot procedure.
