The addition of the Grignard 3,4,5-ArFMgBr to aluminium(III) chloride in ether generates the novel triarylalane Al(3,4,5-ArF)3·OEt2. Attempts to synthesize this alane via 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-ArF)3 was synthesized from the parent borane and trimethylaluminium. Interestingly, the solid-state structure of Al(2,3,4-ArF)3 shows an extended chain structure resulting from neighboring Al···F contacts. Al(3,4,5-ArF)3·OEt2 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.
