Schwefel‐Stickstoff‐Fluorverbindungen. II. Darstellung und Eigenschaften von SNF₃

Abstract

Durch Reaktion eines gasförmigen Gemisches von SNF und SN2F2 mit AgF2 bei Zimmertemperatur und Normaldruck entsteht ein farbloses Gas von der Zusammensetzung SNF3. Fp.: −81°C; Kp.: −23°C; d −804 = 1,92; Verdampfungsenthalpie (mittlere molare): 5211 cal; TROUTONsche Konstante: 20,8. Die Hydrolyse mit NaOH gibt NH +4, F− und SO 2−3‐Ionen.

Ex situ Generation of Thiazyl Trifluoride (NSF3) as a Gaseous SuFEx Hub**

“…[9] Their parent compound, thiazyl trifluoride (NSF 3 ) was first reported by Glemser in 1956. [10] This gaseous molecule (b.p. À 27.1 � 0.1 °C) [11] with a dipole moment of 1.91 D, [12] is significantly more polar than its sulfonyl counterpart SO 2 F 2 (1.11 D).…”

“…Compared to the sulfonimidoyl and the especially well‐studied sulfonyl units, reports on the thiazyl centerpiece as the “third sulfur(VI) core” are sparse (Scheme 1B) [9] . Their parent compound, thiazyl trifluoride (NSF 3 ) was first reported by Glemser in 1956 [10] . This gaseous molecule (b.p.…”

“…This discrepancy may be related to the unavailability of the NSF 3 gas. Existing routes for generation of NSF 3 are marked by prohibitive limitations, such as the use of gaseous (NSF) [8a, 10, 11] or explosive (S 4 N 4 ) [12] starting materials, the use of a high excess of reagents, [19] the need for high temperatures, [10, 12, 20] or the generation of various by‐products requiring further purification of the gas stream [8a, 12, 20, 21] (Scheme 1D). To enable exploration of NSF 3 as a SuFEx hub, it is, therefore, crucial to improve its synthesis, ideally making use of standard laboratory equipment.…”

Ennobling an Old Molecule: Thiazyl Trifluoride (N≡SF3), a Versatile Synthon for Xe–N Bond Formation

“…Thiazyl trifluoride, NSF 3 , is among the first reported compounds containing only sulfur, nitrogen, and fluorine. , Over the 56 years that have elapsed since its discovery, the field of sulfur-nitrogen-fluorine chemistry has grown significantly, and several reviews have been written on the topic; − however, a recent comprehensive review of the topic is unavailable. The present Article focuses on the most recent developments in NSF 3 chemistry and their impacts on noble-gas chemistry.…”

Methoden zur Darstellung kationischer Rhenium-pentacarbonyl(thiazylhalogenid)-Komplexe / Methods for the Preparation of Cationic Rhenium-pentacarbonyl(thiazylhalide) Complexes

“…Vor einiger Zeit konnten wir zeigen, daß das Thiazylfluorid NSF [1] -ebenso wie das Thiazyltrifluorid NSF 3 [2,3] -in der Lage ist, als a-Donor-Ligand zu fungieren. Synthesen und zum Teil auch Strukturuntersuchungen an den homoleptischen Thiazylfluoridkomplexen [M(NSF) 6 ] 2+ (M = Co, Ni) [4,5], [CU(NSF) 4 ] 2+ [6] [8].…”
