Beiträge zur Chemie der Schwefel‐Halogenide. 20. Di(methylthio)methyl‐ und Di(phenylthio)methylsulfonium‐hexafluoroarsenat und ‐hexachloroantimonat

Abstract

Es wird über die Darstellung und spektroskopische Charakterisierung der Di(methylthio)methyl‐ und Di(phenylthio)methylsulfonium‐Salze CH3S(SCH3)2+A− und CH3S(SC6H5)2+A− (A− = AsF6−, SbCl6−) berichtet. Ergänzend wird die Kristallstruktur von Di(methylthio)methylsulfoniumhexafluoroarsenat mitgeteilt.

From Noncovalent Chalcogen–Chalcogen Interactions to Supramolecular Aggregates: Experiments and Calculations

“…3,7 In Figure 6a we show the results of X-ray investigations on the dimers of [Se 2 Me 3 ]TeF 5 (17) 31 and [S 3 Me 3 ]AsF 6 (18a). 32 In Figure 6b a second modification of [S 3 Me 3 ]AsF 6 (18b) 33 is shown, in which four [S 3 Me 3 ] + units form a chain with short S•••S contacts (see Table 2). In the deep red colored salt [Se 3 Me 3 ]SbCl 6 (19) 34 the Se 3 Me 3 + units form a chain with short intermolecular Se•••Se distances.…”

Synthesis and Characterization of the Tris(methylthio)sulfonium Salt [(CH3S)3S]+SbF6-1

“…In the course of our studies of sulfur-rich compounds, synthetic pathways to trithiosulfonium salts were of general interest, since they contain the simplest structural fragment of a three-dimensional sulfur network. During our studies on reaction sequences for the formation of sulfur chains, connected to sulfonium cations, the condensation of S−H functional compounds with chlorosulfonium salts was found to be an excellent general pathway. − The condensation of trichlorosulfonium salts with hydrogen sulfide (eq 1) yielded unstable trismercaptosulfonium salts, but attempts to obtain more stable organyl derivates by the use of mercaptanes failed (eq 1)…”
