Cationic Heterobimetallic Mg(Zn)/Al(Ga) Combinations for Cooperative C-F Bond Cleavage.

ABSTRACT: Low-valent (^Me BDI)Al and (^Me BDI)Ga and highly Lewis acidic cations in [(^tBu BDI)M⁺ ⋅C₆ H₆ ][(B(C₆ F₅ )₄ ^- ] (M=Mg or Zn, ^Me BDI=HC[C(Me)N-DIPP]₂ , ^tBu BDI=HC[C(tBu)N-DIPP]₂ , DIPP=2,6-diisopropylphenyl) react to heterobimetallic cations [(^tBu BDI)Mg-Al(^Me BDI)⁺ ], [(^tBu BDI)Mg-Ga(^Me BDI)⁺ ] and [(^tBu BDI)Zn-Ga(^Me BDI)⁺ ]. These cations feature long Mg-Al (or Ga) bonds while the Zn-Ga bond is short. The [(^tBu BDI)Zn-Al(^Me BDI)⁺ ] cation was not formed. Combined AIM and charge calculations suggest that the me
