NEUE ERGEBNISSE BEI DER SPALTUNG VON THIOETHERN MIT NATRIUM IN FLUESSIGEM AMMONIAK. ABTRENNUNG VON 1.3.5-TRITHIAPENTAN UEBER 1.5-BIS-(TRIMETHYLSILYL)-1.3.5-TRITHIAPENTAN ALS ZWISCHENSTUFE

Recent results show that the cleavage of oligomeric and polymeric thioformaldehydes or polymethylenedisulfide by sodium in liquid ammonia, followed by treatment with an excess of hydrochloric acid, leads to the formation of mercaptothioethers, CH3(SCH2)nSH, bis-mercaptothioethers, HS(CH2S)mH and thioalkanes, CH3(SCH2)xSCH3.The identification and isolation of various components of these mixtures are described.The separation of pure 1.3.5-trithiapentane by silylation, distillation and cleavage with hydrogen chloride is of interest for its synthesis starting from easily available compounds like s-trithiane, polymethylenesulfide or polymethylenedisulfide.The silylated derivatives of 1.3.5-trithiahexane and 1.3.5-trithiapentane are described.
