Donor-free 9,10-dihydro-9,10-dialuminaanthracenes.

ABSTRACT: Despite their promising potential, e.g., as ditopic, cooperatively binding Lewis acids, 9,10-dihydro-9,10-dialuminaanthracenes (DAA-R₂; R: terminal Al-bonded substituent) have remained unexplored for long due to the challenges in synthesizing the ligand-free species. We demonstrate that DAA-Me₂ is accessible via the reaction of 1,2-(Me₃Sn)₂C₆H₄ with AlMe₃, producing volatile SnMe₄ as the sole byproduct. In non-coordinating solvents and in the solid state, DAA-Me₂ exists as a dimer (DAA-Me₂)₂. Treatment of (DAA-Me₂)₂ with 4 equiv. AlBr₃ cleaves the dimer, leads to quantitative Me/Br exchange, and forms the double AlBr_3</
