Seven-Membered Cyclic Potassium Diamidoalumanyls.

ABSTRACT: The seven-membered cyclic potassium alumanyl species, [{SiN^Mes }AlK]₂ [{SiN^Mes }={CH₂ SiMe₂ N(Mes)}₂ ; Mes=2,4,6-Me₃ C₆ H₂ ], which adopts a dimeric structure supported by flanking K-aryl interactions, has been isolated either by direct reduction of the iodide precursor, [{SiN^Mes }AlI], or in a stepwise manner via the intermediate dialumane, [{SiN^Mes }Al]₂ . Although the intermediate dialumane has not been observed by reduction of a Dipp-substituted analogue (Dipp=2,6-i-Pr₂ C₆ H₃ ), partial oxidation of the potassium alumanyl species, [{SiN^Dipp }AlK]₂ , where {SiN^Dipp }={CH₂ SiMe
