The diaminoferrocene derivatives [Fe{(η 5 ‐C 5 H 4 )NH R } 2 ] ( 1 H 2 , a : R = SiMe 2 t Bu, b : R = CMe 2 t Bu, c : R = C 6 H 3 ‐2,6‐ i Pr 2 ) were converted into the lithium amides 1a Li 2 – 1c Li 2 by treatment with n BuLi. The reaction of these amides with AlI 3 furnished 1a AlI – 1c AlI. The reduction of 1a AlI with KC 8 afforded 1a Al–Al 1a , which is a new stable dialumane(4) with exclusively tricoordinate Al atoms and only the second example so far of a tetraamino‐substituted compound of this kind. 1b H 2 , 1c H 2 , 1a Li 2 , [ 1c {Li(THF) 3 } 2 ], [ 1a AlI(OEt 2 )], 1c AlI, 1a Al–Al 1a· ½Et 2 O and 1a Al–Al 1a· ½C 7 H 8 were structurally characterized by single‐crystal X‐ray diffraction.
