Darstellung von Cyclopentadekaschwefel (S15) aus Titanocenpentasulfid und Sulfurylchlorid [1]

Abstract: Titanocene pentasulfide reacts with sulfuryl chloride under suitable conditions to give a mixture of mainly S10, S15, and S20 which can be separated by repeated crystallization and precipitation. Pure S15 is obtained as a lemon-yellow powder at low temperatures which transforms to a sticky mass at 20 °C. Solutions of S15 in CS2 are stable at 20 °C for months. Pure S15 does not decompose at 20 °C within a few hours. Raman spectra of S15 show stretching vibrations at 409-480 cm-1 and bending and torsional modes … Show more

“…It bears mention here that many other allotropes of sulfur have been prepared, structurally authenticated by X-ray crystallography, and characterized by other means. Of these allotropes, which include S 6 , S 7 , S 9 , S 10 , 55a, S 11 , S 12 , S 13 ,58bc S 14 , S 15 , S 18 , 55e,59d, and S 20 , 55e,59d,62a, S 6 is most amenable to preparative scale synthesis 54a…”

“…Linien von S 8 oder S 12 [13] sind nicht nachweisbar. Das Umkehrphasen-HPLC-Chromatogramm von reinem S 14 enthält nur ein groûes Signal, dessen Retentionszeit zwischen denen von S 13 [8] und S 15 [14] liegt. Mit dieser Analysenmethode waren Spuren von S 14 bereits früher in abgeschreckten Schwefelschmelzen und in synthetischen Schwefelmischungen detektiert worden.…”

“…In further studies mixtures or pure dichloropolysulfanes S n Cl 2 ( n =2–17) were treated with [Cp 2 Ti(S 5 )] ( 22 ) to result in sulfur cycles S 5+ n , whereas S y ( y =9, 11, 12, 13) was crystallized from product mixtures . When SO 2 Cl 2 reacts with the titanocenium polysulfide 22 , S 10 , S 20 and small amounts of S 15 are formed with release of SO 2 …”
