Preparation of Piperidinosulfur Trifluoride and of New Aminosulfur(IV) Monofluoride ImidesC5H10NSF3 (1c) is formed in the reaction of SF4 with C5H10NSi(CH3)3. Aminosulfur(IV)-trifluorides of the type R—SF3 (R=N(CH3)2 (1a), N(C2H5)2 (1b), or NC5H10 (1c)) react with the bis(trimethylsiyl)compounds (CH3)3SiNCNSi(CH3)3, CF3C[OSi( CH3)3]=NSi(CH3)3, or CH3N[Si(CH3)3]2 yielding aminosulfur(IV) monofluoride imides, NC—N=S(F)NC5H10 (2c), CF3CO—N=S(F)R (3a—c), and CH3N=S(F)R (4b). The reaction of silylamines with (CF3)2C(F)N=SF2 yields also aminosulfur(IV) monofluoride imides of the type (CF3)2C(F)N S(F)R (5a—c). In the reaction of (CF3)2C(F)N=SF2 with an excess of (CH3)2NSi(CH3)3 the new sulfur diimide [(CF3)2C[N(CH3)2]N=]2S (6) is formed. The 19Fn.m.r., the 1H n.m.r., and the i.r. spectra are reported.
Notes:
C5H10NSF3 (1c) erhält man bei der Reaktion von SF4 mit C5H10NSi(CH3)3. Aminoschwefel-(IV)-trifluoride vom Typ R— SF3 (R=N(CH3)2 (1a), N(C2H5)2 (1b) oder NC5H10 (1c)) reagieren mit den Bis(trimethylsilyl)-Verbindungen (CH3)3SiNCNSi(CH3)3, CF3C[OSi(CH3)3]=NSi(CH3)3 oder CH3N[Si(CH3)3]2 zu den entsprechenden Aminoschwefel(IV)-monofluoridimiden: NC—N=S(F)NC5H10 (2c), CF3CO—N=S(F)R (3a-c) und CH3N=S(F)R (4b). Die Reaktion von Silylaminen mit (CF3)2C(F)N=SF2 führt ebenfalls zu Aminoschwefel(IV)-monofluoridimiden, (CF3)2C(F)N=S(F)R (5a—c). Läßt man N-Heptafluorisopropyl-schwefeldifluoridimid mit einem Überschuß an Trimethylsilyl-dimethyl-amin reagieren, erhält man das neue Schwefeldiimid [(CF3)2C[N(CH3)2]N=]2S (6). Die 19F-NMR-, 1H-NMR- und IR-Spektren der neuen Verbindungen werden mitgeteilt.
