摘要：

[(C5Me5)LnMe(2)](3) (Ln = Y, Lu) dissolve readily in a n-hexane/toluene mixture upon addition of 3 equiv of the organoaluminum boryl compound [Me2Al{B(NDippCH)(2)}](2) (Dipp = C(6)H(3)iPr(2)-2,6). The half-sandwich complexes (C5Me5)Ln[(AlMe3){B(NDippCH)(2)}](2) thus formed display unsymmetrical heteroaluminate coordination not only in the solid state but also at lower temperatures in solution, which is distinct from the behavior of the homoaluminate congeners (C5Me5)Ln(AlMe4)(2). The effect of homo- versus heteroaluminate coordination is assessed in the coordinative polymerization of isoprene.
