ABSTRACT
A series of low-valent Group 14-15 compounds were obtained starting from [(Dipp2 NacNac)MCl] (M=Ge-Pb) (I-III) (Dipp2 NacNac=HC{C(Me)N(Dipp)}2 ) and M'E(SiMe3 )2 (M'=Li, E=As; M'=K, E=Sb, Bi) (IV-VI). In the course of this investigations we were able to fully characterize all permutations except Pb-Bi for compounds of the composition [(Dipp2 NacNac)ME(SiMe3 )2 ] (1E M=Ge, 2E M=Sn, 3E M=Pb). Thus, we report the first low valent tetrelene with Sn-Bi bond. All isolated compounds, were examined by NMR spectroscopy, IR spectroscopy and except compound 1As by X-ray structure analysis. Moreover, were examined UV-Vis spectroscopy and investigated the reactivity of these compounds towards different substrates in more detail. Starting with the compound [(Dipp2 NacNac)SnAs(SiMe3 )2 ] (2As ), the reaction with red selenium yields [(Dipp2 NacNac)Sn-Se-As(SiMe3 )2 ] (4) which exhibits a Sn-Se-As chain.
