Synthesis of Lewis Acid‐Base Adducts Between Potassium Dihydrogenpnictogenides and Group 13 Lewis Acids
Lewis acid-base adducts between potassium dihydrogenpnictogenides [K(18c6)PnH<sub>2</sub>] (Pn=P, As) and Trialkylgallanes (GaMe<sub>3</sub>, GaEt<sub>3</sub>, GatBu<sub>3</sub>) as well as BH<sub>3</sub> were synthesized. In the course of these investigations, we were able to fully characterize a row of compounds of the type [K(18c6)(thf)<sub>0-2</sub>][PnH<sub>2</sub>(ER<sub>3</sub>)<sub>2</sub>] (E=B: R=H; E=Ga: R=Me, Et, tBu). Based on the successful syntheses of these species, we also synthesized several compounds of the composition [K(18c6)(thf)<sub>0-2</sub>][Pn(SiMe<sub>3</sub>)<sub>2</sub>(ER<sub>3</sub>)<sub>n</sub>] (n=1, 2) starting from [KPn(SiMe<sub>3</sub>)<sub>2</sub>] (Pn=P and As) and ER<sub>3</sub> (E=B, Al, In: R=Me; E=Ga: R=Me, Et, tBu). All isolated compounds, were examined by NMR spectroscopy, infra-red spectroscopy and elemental analysis. A selection of the compounds presented were also examined by means of X-ray structure analysis on the single crystal. The obtained adducts of negatively charged [PnH<sub>2</sub>]<sup>-</sup> and [Pn(SiMe<sub>3</sub>)<sub>2</sub>]<sup>-</sup> fragments with Lewis acids are a class of compounds that has scarcely been investigated to date.
