The half-open rare-earth-metal aluminabenzene complexes [(1-Me-3,5-tBu -C H Al)(μ-Me)Ln(2,4-dtbp)] (Ln=Y, Lu) are accessible via a salt metathesis reaction employing Ln(AlMe ) and K(2,4-dtbp). Treatment of the yttrium complex with B(C F ) and tBuCCH gives access to the pentafluorophenylalane complex [{1-(C F )-3,5-tBu -C H Al}{μ-C F }Y{2,4-dtbp}] and the mixed vinyl acetylide complex [(2,4-dtbp)Y(μ-η :η -2,4-tBu -C H )(μ-CCtBu)AlMe ], respectively.
半开放的稀土金属铝苯配合物[(1-甲基-3,5-二叔丁基- C₆H₃Al)(μ-甲基)Ln(2,4-二叔丁基吡啶)] (Ln = Y, Lu) 可通过使用Ln(AlMe₄) 和K(2,4-二叔丁基吡啶) 的盐复分解反应得到。用B(C₆F₅)₃和叔丁基乙炔处理钇配合物，分别得到五氟苯铝配合物[{1-(C₆F₅)-3,5-二叔丁基- C₆H₃Al}{μ-C₆F₅}Y{2,4-二叔丁基吡啶}] 和混合乙烯基乙炔配合物[(2,4-二叔丁基吡啶)Y(μ-η²:η²-2,4-二叔丁基- C₆H₂)(μ-C≡CtBu)AlMe₂]。
