<p>The addition of the Grignard 3,4,5-Ar<sup>F</sup>MgBr to aluminium(III) chloride in ether generates the novel triarylalane Al(3,4,5-Ar<sup>F</sup>)<sub>3</sub>·OEt<sub>2</sub>. Attempts to synthesize this alane <em>via</em> transmetallation from the parent borane with trimethylaluminium gave a dimeric structure with bridging methyl groups; a product of partial transmetallation. On the other hand, the novel alane Al(2,3,4-Ar<sup>F</sup>)<sub>3</sub> was synthesized from the parent borane and trimethylaluminium. Interestingly, the solid-state structure of Al(2,3,4-Ar<sup>F</sup>)<sub>3 </sub>shows an extended chain structure resulting from neighboring Al···F contacts. Al(3,4,5-Ar<sup>F</sup>)<sub>3</sub>·OEt<sub>2 </sub>was then found to be an effective catalyst for the hydroboration of carbonyls, imines and alkynes with pinacolborane. Data include experimental procedures, NMR data, X-ray data and computational data.</p><p>Research results based upone these data are published at https://doi.org/10.1021/acs.inorgchem.0c01076<br></p><p><br></p>
