1,2,4-Tri(<sup><i>t</i></sup>Bu)cyclopentadienyl gallium (Cp′′′Ga) as a versatile reagent for the synthesis of Lewis adducts and ionic compounds
The reaction of (η<sup>5</sup>-1,2,4-tri(<sup><i>t</i></sup>Bu)cyclopentadienyl)gallium (Cp'''Ga; 1) with boron(III) species resulted in a diversity of complexes with different oxidation states and coordination modes, respectively. The reaction of 1 with triarylborane B(C<sub>6</sub>F<sub>5</sub>)<sub>3</sub> readily forms η<sup>5</sup>-Cp'''Ga → B(C<sub>6</sub>F<sub>5</sub>)<sub>3</sub> (2) adducts, where gallium exhibits a +I oxidation state. However, using the bulky substituted borane halide (TipBBr<sub>2</sub>) leads to the formation of an ionic compound, [η<sup>5</sup>-Cp'''B-Tip]<sup>+</sup>[GaBr<sub>4</sub>]<sup>-</sup> (3). Furthermore, the reaction of 1 with BI<sub>3</sub> experiences unforeseen insertion of the boron atom between the Cp''' ring and Ga that produces η<sup>5</sup>-Cp'''B → GaI<sub>3</sub> adduct (4). All new compounds were fully characterized by multinuclear NMR, elemental analysis, and X-ray diffraction.
