triethoxy-[3-(3-triethoxysilylpropyltrisulfanyl)propyl]silane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 47.5 g of bis-[γ-(triethoxysilyl)-propyl]-disulfide (0.1 mole) was heated together with 3.2 g of sulfur (0.1 mole) under a nitrogen gas atmosphere for about 15 hours at about 150°C, until all of the sulfur had dissolved and did not crystallize out again upon cooling. A dark red liquid was formed, which a thin-layer chromatogram showed to contain no free sulfur, and in which disulfides and tetrasulfides are dissolved as shown by mass spectrographic analysis. did not crystallize out again upon cooling A dark red liquid was formed
