Conclusions

Trialkoxysilylalkanethiols (CH3O)3Si(CH2)nSH (n=1–3) react with divinyl sulfide at 100–110° to give 2-(trialkoxysilylalkylthio)ethyl vinyl sulfides (CH3O)3Si(CH2)nS (CH2)2SCH=CH2 in high yield. The reactivity of the trialkoxysilylalkanethiols decreases with increase in the number of CH2 groups between the S and Si atoms. A second molecule of the organosilicon thiol acids adds with difficulty to divinyl sulfide to give the diadduct.
