    Description / Table of Contents: Preparation of new Thiazyltrifluoride Derivatives by Si-N Bond Cleavage Reactions. Preparation of N.N'-Bis(difluorophosphoryl)sulfur Difluoride DiimideBy Si-N bond cleavage reactions with thiazyltrifluoride NSF2-N(CH3)2 (3) and NSF2-N(C2H5)2 (4) were prepared. (CH3)3Si-N=SF2=N-Si(CH3)3 (1) react with SF4 to yield NSF2-N=SF2 (5), with P2O3F4 to give O=PF2-N=SF2=N-PF2=O (6) and small amounts of (CH3)3Si-N=SF2=N-PF2=O (7). By reaction of 1 with dimethylamine and piperidine [CH3)3Si-N=]2S[N(CH3)2]2 (8) and [(CH3)3Si-N=]2S(NC5H10)2 (9) are formed.
    Notes: Durch Si-N-Spaltungsreaktionen mit Thiazyltrifluorid wurden NSF2—N(CH3)2 (3) und NSF2—N(C2H5)2 (4) dargestellt. Aus (CH3)3Si—N=SF2=N—Si(CH3)3 1) entsteht mit SF4 NSF2—N=SF2 (5), mit P2O3F4 O=PF2-N=SF2=N-PF2=O (6) neben geringen Mengen (CH3)3Si—N=SF2=N—PF2—O(7). Die Reaktionen von 1 mit Dimethylamin und mit Piperidin führt zu [(CH3)3Si-N=]2S[N(CH3)2]2 (8) bzw. zu [(CH3)3Si-N=]2S(NC5H10)2 (9).
