Edit. 4,5-Bis(trimethylsilyl)-1,2,3-trithiole (32) was formed in 5% yield from the thermal reaction of 1,2-bis(trimethylsilyl)ethyne with elemental sulfur 〈93BCJ623〉; the low yield of this product was attributed to extensive CSi bond cleavage taking place under the reaction conditions. CNDO/2 calculations have also been carried out on the monomer 〈81JA7458〉. Treatment of 1,2-dihydroxyethane or higher 1,2-diols with S2Cl2 〈65JOC2696〉, or with the sulfur transfer agent, thiobis(benzimidazole) 〈80CC825〉, afforded 1,3,2-dioxathiolane 2-thiones.

Solution for How many moles of sulfur dichloride are present in 2.74 grams of this compound?… The table shows element percentages for S 3 Cl 2 (trisulphur dichloride). Caserio reported that when alkenes are treated with a sulfenamide such as MeSNMe2 in the presence of the Meerwein reagent trimethyloxonium tetrafluoroborate, azasulfenylation of the alkene is observed, presumably via the thioammonium ion MeSNMe3+ (equation 4).20 Boron trifluoride etherate can also serve as a catalyst for addition of sulfenamides to alkenes. It has also been reported to undergo a number of interesting reactions with alkynes, but it is difficult to determine if the reaction occurs from monomer (S2N2) or dimer (S4N4) 〈79JHC1009〉.
