The half‐open rare‐earth‐metal aluminabenzene complexes [(1‐Me‐3,5‐ t Bu 2 ‐C 5 H 3 Al)(μ‐Me)Ln(2,4‐dtbp)] (Ln=Y, Lu) are accessible via a salt metathesis reaction employing Ln(AlMe 4 ) 3 and K(2,4‐dtbp). Treatment of the yttrium complex with B(C 6 F 5 ) 3 and t BuCCH gives access to the pentafluorophenylalane complex [{1‐(C 6 F 5 )‐3,5‐ t Bu 2 ‐C 5 H 3 Al}{μ‐C 6 F 5 }Y{2,4‐dtbp}] and the mixed vinyl acetylide complex [(2,4‐dtbp)Y(μ‐η 1 :η 3 ‐2,4‐ t Bu 2 ‐C 5 H 4 )(μ‐CC t Bu)AlMe 2 ], respectively.
