Abstract

The reaction between MHal4 (M = Ge, Sn; Hal = Cl, Br) and N(CH2CH2NRLi)3 (R = Me, SiMe3) yields 1-haloazametallatranes 1−8, N(CH2CH2NR)3M−Hal (1, M = Ge, Hal = Cl, R = Me; 2, M = Ge, Hal = Br, R = Me; 3, M = Ge, Hal = Cl, R = SiMe3; 4, M = Ge, Hal = Br, R = SiMe3; 5, M = Sn, Hal = Cl, R = Me; 6, M = Sn, Hal = Br, R = Me; 7, M = Sn, Hal = Cl, R = SiMe3; 8, M = Sn, Hal = Br, R = SiMe3). The composition and structures of the new compounds were established by elemental analyses, 1H and 13C NMR spectroscopy and mass spectrometry. Single crystal structures of 1 and 3 were determined by X-ray diffraction studies: both compounds show transannular Ge−Nax interactions. (© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
