Temperature‐Dependent Electron Shuffle in Molecular Group 13/15 Intermetallic Complexes

Monovalent RAl (R=HC[C(Me)N(2,6‐ i Pr 2 C 6 H 3 )] 2 ) reacts with E 2 Et 4 (E=Sb, Bi) with insertion into the weak EE bond and subsequent formation of RAl(EEt 2 ) 2 (E=Sb 1 ; Bi 2 ). The analogous reactions of RGa with E 2 Et 4 yield a temperature‐dependent equilibrium between RGa(EEt 2 ) 2 (E=Sb 3 ; Bi 4 ) and the starting reagents. RIn does not interact with Sb 2 Et 4 under various reaction conditions, but formation of RIn(BiEt 2 ) 2 ( 5 ) was observed in the reaction with Bi 2 Et 4 at low temperature.
