Annulated carbocyclic gallylene and bis-gallylene with two-coordinated Ga(i) atoms.

ABSTRACT: The first carbocyclic gallylene [(ADC)₂Ga(GaI₂)] and bis-gallylene [(ADC)Ga]₂ (ADC = PhC{N(Dipp)C}₂; Dipp = 2,6-iPr₂C₆H₃) featuring a central C₄Ga₂ ring annulated between two 1,3-imidazole rings are prepared by KC₈ reductions of [(ADC)GaI₂]₂. Treatment of [(ADC)Ga]₂ with Fe₂(CO)₉ affords complex [(ADC)GaFe(CO)₄]₂ in which each Ga(i) atom serves as a two-electron donor. [(ADC)Ga]₂ activates white phosphorus (P₄) and the C_sp² -F bond of aryl fluorides (ArF) to yield compounds [(ADC)Ga(P₄)]₂ and cis-/trans-[(ADC)GaF(Ar)]₂
