  Why propene is not polymerized by (Cp*2YH)2: reactions of yttrium alkyl complexes with alkenes produce allyl and vinyl yttrium complexes

  摘要：

  Yttrium alkyl complexes (Cp2YR)-Y-* react with C-H bonds of alkenes to form either yttrium allyl complexes or yttrium vinyl complexes. Less substituted alkenes react faster, consistent with prior alkene coordination. The selectivity of the reaction of (Cp2YR)-Y-* with C-H bonds is allylic CH3 much greater than vinyl C-H much greater than allylic CH2. Propene is readily metallated by (Cp2YR)-Y-* giving the eta(3)-allyl complex (Cp2Y)-Y-*(eta(3)-CH2 - CH - CH2) which does not react further with propene. This explains why (Cp2YR)-Y-* (R = alkyl, H) complexes make poor propene polymerization catalysts. (C) 2002 Elsevier Science B.V. All rights reserved.

  Alkene Dissociation from a d⁰ Yttrocene−Alkyl−Alkene Complex Generates a Pyramidal Alkyl Yttrium Complex That Inverts Slowly

  摘要：

  The d(0) yttrium(III)-alhyl-alkene chelate Cp*Y-2[eta(1):eta(2)-CH2CH2CH(CH3)CH=CH2] (5) was prepared by reaction of 3-methyl-1,4-pentadiene with (Cp*(2)-YH)(2). VariabLe-temperature C-13 NMR spectroscopy of 5 showed that the environments of the two diastereotopic Cp* ligands were averaged by a fluxional process which requires both reversible alkene dissociation and inversion at the yttrium center; the energy barrier fur alkene dissociation pins yttrium inversion is 9.6 +/- 0.3 kcal mol(-1).
