N-Silylaminotin Trichlorides. Synthesis and Characterisation by Multinuclear Magnetic Resonance Spectroscopy

Bernd Wrackmeyer, Andreas Pedall and Jürgen Weidinger

N-Silyl-aminotin trichlorides, R1R2N-SnCl3[R1 = R2 = SiMe3 (1a), R1 = SiMe3, R2 = tBu (1b), R = SiMe3, R2 = 9-borabicyclo[3.3.1]nonyl (1c), R1R2 = Me2 SiCH2CH2SiMe2 (1d)] were prepared by the reaction of tin tetrachloride with the respective bis(amino)plumbylenes, (R1R2N)2Pb 4. The analogous reactions with bis(amino)stannylenes, (R1R2N)2Sn 3, afforded only mixtures of the aminotin trichlorides 1 and bis(amino)tin dichlorides, (R1R2N)2 SnCl2 2 . The products were characterised by 1H, 11B, 13C, 15N, 29Si and 119Sn NMR spectroscopy, and the NMR data of 1 were compared with those of the corresponding N-silylamino(trimethyl)tin compounds 8.
