Abstract

Two alternative reaction pathways have been identified in the nucleophilic substitution reactions of Group 14 metallocenes with lithiated primary amines [RNHLi]. These are exemplified by the syntheses and structures of the tris(amido)stannate [(MANH)Sn(μ-NHMA)₂Li.2THF] 1, obtained by the reaction of [(MA)NHLi] with [Cp₂Sn] (MA = 2-MeOC₆H₄), and the cubanes [E(NCy)]₄ (E = Sn 2, Pb 3; Cy = C₆H₁₁), prepared from [CyNHLi] and [Cp₂E]. The latter furnishes a new route to Group 14 imido cubanes.
