Methods for preparation of disilathianes

Article abstract of DOI:10.1080/10426500108045265

Several literature methods for preparation of disilathianes were reexamined and new procedures were developed. Two methods especially useful for the preparation of hexamethyldisilathiane were the reaction between lithium metal, sulfur, and TMS chloride in THF, and the reaction between Li₂S and TMS chloride in THF at room temperature. These two procedures may also be used to prepare other hexaalkyldisilathianes. Other methods investigated for the preparation of hexamethyldisilathiane included (a) reaction between commercial anhydrous Na₂S and TMS chloride in N,N'-dimethylpropyleneurea or HMPA, (b) production of a highly-reactive Na₂S by reaction between sodium dispersion and sulfur, followed by reaction with TMS chloride in THF at room temperature, and (c) reaction between sulfur, NaH, and TMS chloride in N,N'-dimethylpropyleneurea.
