Abstract

Ph₃SnN(SiMe₃)₂ (1) was prepared in good yields by reaction of [{NaN(SiMe₃)₂}₂·THF] (2) with Ph₃SnF. Treatment of 1 with [H(OEt₂)₂][H₂N{B(C₆F₅)₃}₂] (4) in dichloromethane afforded the stannylium cation [Ph₃Sn(OEt₂)][H₂N{B(C₆F₅)₃}₂] (5), which was characterised by ¹H, ¹³C{¹H}, ¹¹B, ¹⁹F and ¹¹⁹Sn NMR spectroscopy. The reaction of Sn(NMe₂)₄ with [Ph₂MeNH][B(C₆F₅)₄] (3) gave the amidotin(IV) compound [Sn(NMe₂)₃(HNMe₂)₂][B(C₆F₅)₄] (6) which proved very stable towards ligand substitution and resisted treatment with Et₂O, THF, TMEDA and pyrazine. Two new Brønsted acid salts [H(NMe₂H)₂][B(C₆F₅)₄] (7) and [(C₄H₄N₂)H·OEt₂][H₂N{B(C₆F₅)₃}₂] (8) were synthesised. The reaction of 7 with Sn(NMe₂)₄ in Et₂O allowed the preparation of 6 in a much improved yield (83?%). The treatment of 7 with Me₃SnN(SiMe₃)₂ in Et₂O yielded [Me₃Sn(HNMe₂)₂][B(C₆F₅)₄] (9) nearly quantitatively. Compounds 1, 2, 6, 8 and 9 were characterised by single-crystal X-ray diffraction analyses; 6 is the first example of a structurally characterised amidotin(IV)cation.(© Wiley-VCH Verlag GmbH & Co.
